+ \class QDate
+ \reentrant
+ \brief The QDate class provides date functions.
+
+
+ A QDate object contains a calendar date, i.e. year, month, and day
+ numbers, in the Gregorian calendar. (see \l{QDate G and J} {Use of
+ Gregorian and Julian Calendars} for dates prior to 15 October
+ 1582). It can read the current date from the system clock. It
+ provides functions for comparing dates, and for manipulating
+ dates. For example, it is possible to add and subtract days,
+ months, and years to dates.
+
+ A QDate object is typically created either by giving the year,
+ month, and day numbers explicitly. Note that QDate interprets two
+ digit years as is, i.e., years 0 - 99. A QDate can also be
+ constructed with the static function currentDate(), which creates
+ a QDate object containing the system clock's date. An explicit
+ date can also be set using setDate(). The fromString() function
+ returns a QDate given a string and a date format which is used to
+ interpret the date within the string.
+
+ The year(), month(), and day() functions provide access to the
+ year, month, and day numbers. Also, dayOfWeek() and dayOfYear()
+ functions are provided. The same information is provided in
+ textual format by the toString(), shortDayName(), longDayName(),
+ shortMonthName(), and longMonthName() functions.
+
+ QDate provides a full set of operators to compare two QDate
+ objects where smaller means earlier, and larger means later.
+
+ You can increment (or decrement) a date by a given number of days
+ using addDays(). Similarly you can use addMonths() and addYears().
+ The daysTo() function returns the number of days between two
+ dates.
+
+ The daysInMonth() and daysInYear() functions return how many days
+ there are in this date's month and year, respectively. The
+ isLeapYear() function indicates whether a date is in a leap year.
+
+ \section1
+
+ \target QDate G and J
+ \section2 Use of Gregorian and Julian Calendars
+
+ QDate uses the Gregorian calendar in all locales, beginning
+ on the date 15 October 1582. For dates up to and including 4
+ October 1582, the Julian calendar is used. This means there is a
+ 10-day gap in the internal calendar between the 4th and the 15th
+ of October 1582. When you use QDateTime for dates in that epoch,
+ the day after 4 October 1582 is 15 October 1582, and the dates in
+ the gap are invalid.
+
+ The Julian to Gregorian changeover date used here is the date when
+ the Gregorian calendar was first introduced, by Pope Gregory
+ XIII. That change was not universally accepted and some localities
+ only executed it at a later date (if at all). QDateTime
+ doesn't take any of these historical facts into account. If an
+ application must support a locale-specific dating system, it must
+ do so on its own, remembering to convert the dates using the
+ Julian day.
+
+ \section2 No Year 0
+
+ There is no year 0. Dates in that year are considered invalid. The
+ year -1 is the year "1 before Christ" or "1 before current era."
+ The day before 0001-01-01 is December 31st, 1 BCE.
+
+ \section2 Range of Valid Dates
+
+ The range of valid dates is from January 2nd, 4713 BCE, to
+ sometime in the year 11 million CE. The Julian Day returned by
+ QDate::toJulianDay() is a number in the contiguous range from 1 to
+ \e{overflow}, even across QDateTime's "date holes". It is suitable
+ for use in applications that must convert a QDateTime to a date in
+ another calendar system, e.g., Hebrew, Islamic or Chinese.

+ \class QTime
+ \reentrant
+
+ \brief The QTime class provides clock time functions.
+
+
+ A QTime object contains a clock time, i.e. the number of hours,
+ minutes, seconds, and milliseconds since midnight. It can read the
+ current time from the system clock and measure a span of elapsed
+ time. It provides functions for comparing times and for
+ manipulating a time by adding a number of milliseconds.
+
+ QTime uses the 24-hour clock format; it has no concept of AM/PM.
+ Unlike QDateTime, QTime knows nothing about time zones or
+ daylight savings time (DST).
+
+ A QTime object is typically created either by giving the number
+ of hours, minutes, seconds, and milliseconds explicitly, or by
+ using the static function currentTime(), which creates a QTime
+ object that contains the system's local time. Note that the
+ accuracy depends on the accuracy of the underlying operating
+ system; not all systems provide 1-millisecond accuracy.
+
+ The hour(), minute(), second(), and msec() functions provide
+ access to the number of hours, minutes, seconds, and milliseconds
+ of the time. The same information is provided in textual format by
+ the toString() function.
+
+ QTime provides a full set of operators to compare two QTime
+ objects. One time is considered smaller than another if it is
+ earlier than the other.
+
+ The time a given number of seconds or milliseconds later than a
+ given time can be found using the addSecs() or addMSecs()
+ functions. Correspondingly, the number of seconds or milliseconds
+ between two times can be found using secsTo() or msecsTo().
+
+ QTime can be used to measure a span of elapsed time using the
+ start(), restart(), and elapsed() functions.

+/*!
+ \class QDateTime
+ \reentrant
+ \brief The QDateTime class provides date and time functions.
+
+
+ A QDateTime object contains a calendar date and a clock time (a
+ "datetime"). It is a combination of the QDate and QTime classes.
+ It can read the current datetime from the system clock. It
+ provides functions for comparing datetimes and for manipulating a
+ datetime by adding a number of seconds, days, months, or years.
+
+ A QDateTime object is typically created either by giving a date
+ and time explicitly in the constructor, or by using the static
+ function currentDateTime() that returns a QDateTime object set
+ to the system clock's time. The date and time can be changed with
+ setDate() and setTime(). A datetime can also be set using the
+ setTime_t() function that takes a POSIX-standard "number of
+ seconds since 00:00:00 on January 1, 1970" value. The fromString()
+ function returns a QDateTime, given a string and a date format
+ used to interpret the date within the string.
+
+ The date() and time() functions provide access to the date and
+ time parts of the datetime. The same information is provided in
+ textual format by the toString() function.
+
+ QDateTime provides a full set of operators to compare two
+ QDateTime objects where smaller means earlier and larger means
+ later.
+
+ You can increment (or decrement) a datetime by a given number of
+ seconds using addSecs(), or days using addDays(). Similarly you can
+ use addMonths() and addYears(). The daysTo() function returns the
+ number of days between two datetimes, and secsTo() returns the
+ number of seconds between two datetimes.
+
+ QDateTime can store datetimes as \l{Qt::LocalTime}{local time} or
+ as \l{Qt::UTC}{UTC}. QDateTime::currentDateTime() returns a
+ QDateTime expressed as local time; use toUTC() to convert it to
+ UTC. You can also use timeSpec() to find out if a QDateTime
+ object stores a UTC time or a local time. Operations such as
+ addSecs() and secsTo() are aware of daylight saving time (DST).
+
+ \note QDateTime does not account for leap seconds.
+
+ \section1
+
+ \target QDateTime G and J
+ \section2 Use of Gregorian and Julian Calendars
+
+ QDate uses the Gregorian calendar in all locales, beginning
+ on the date 15 October 1582. For dates up to and including 4
+ October 1582, the Julian calendar is used. This means there is a
+ 10-day gap in the internal calendar between the 4th and the 15th
+ of October 1582. When you use QDateTime for dates in that epoch,
+ the day after 4 October 1582 is 15 October 1582, and the dates in
+ the gap are invalid.
+
+ The Julian to Gregorian changeover date used here is the date when
+ the Gregorian calendar was first introduced, by Pope Gregory
+ XIII. That change was not universally accepted and some localities
+ only executed it at a later date (if at all). QDateTime
+ doesn't take any of these historical facts into account. If an
+ application must support a locale-specific dating system, it must
+ do so on its own, remembering to convert the dates using the
+ Julian day.
+
+ \section2 No Year 0
+
+ There is no year 0. Dates in that year are considered invalid. The
+ year -1 is the year "1 before Christ" or "1 before current era."
+ The day before 0001-01-01 is December 31st, 1 BCE.
+
+ \section2 Range of Valid Dates
+
+ The range of valid dates is from January 2nd, 4713 BCE, to
+ sometime in the year 11 million CE. The Julian Day returned by
+ QDate::toJulianDay() is a number in the contiguous range from 1 to
+ \e{overflow}, even across QDateTime's "date holes". It is suitable
+ for use in applications that must convert a QDateTime to a date in
+ another calendar system, e.g., Hebrew, Islamic or Chinese.
+
+ The Gregorian calendar was introduced in different places around
+ the world on different dates. QDateTime uses QDate to store the
+ date, so it uses the Gregorian calendar for all locales, beginning
+ on the date 15 October 1582. For dates up to and including 4
+ October 1582, QDateTime uses the Julian calendar. This means
+ there is a 10-day gap in the QDateTime calendar between the 4th
+ and the 15th of October 1582. When you use QDateTime for dates in
+ that epoch, the day after 4 October 1582 is 15 October 1582, and
+ the dates in the gap are invalid.
+
+ \section2
+ Use of System Timezone
+
+ QDateTime uses the system's time zone information to determine the
+ offset of local time from UTC. If the system is not configured
+ correctly or not up-to-date, QDateTime will give wrong results as
+ well.
+
+ \section2 Daylight Savings Time (DST)
+
+ QDateTime takes into account the system's time zone information
+ when dealing with DST. On modern Unix systems, this means it
+ applies the correct historical DST data whenever possible. On
+ Windows and Windows CE, where the system doesn't support
+ historical DST data, historical accuracy is not maintained with
+ respect to DST.
+
+ The range of valid dates taking DST into account is 1970-01-01 to
+ the present, and rules are in place for handling DST correctly
+ until 2037-12-31, but these could change. For dates falling
+ outside that range, QDateTime makes a \e{best guess} using the
+ rules for year 1970 or 2037, but we can't guarantee accuracy. This
+ means QDateTime doesn't take into account changes in a locale's
+ time zone before 1970, even if the system's time zone database
+ supports that information.

+
+ These expressions may be used for the date part of the format string:
+
+ \table
+ \header \i Expression \i Output
+ \row \i d \i the day as number without a leading zero (1 to 31)
+ \row \i dd \i the day as number with a leading zero (01 to 31)
+ \row \i ddd
+ \i the abbreviated localized day name (e.g. 'Mon' to 'Sun').
+ Uses QDate::shortDayName().
+ \row \i dddd
+ \i the long localized day name (e.g. 'Monday' to 'Sunday').
+ Uses QDate::longDayName().
+ \row \i M \i the month as number without a leading zero (1-12)
+ \row \i MM \i the month as number with a leading zero (01-12)
+ \row \i MMM
+ \i the abbreviated localized month name (e.g. 'Jan' to 'Dec').
+ Uses QDate::shortMonthName().
+ \row \i MMMM
+ \i the long localized month name (e.g. 'January' to 'December').
+ Uses QDate::longMonthName().
+ \row \i yy \i the year as two digit number (00-99)
+ \row \i yyyy \i the year as four digit number
+ \endtable
+
+ \note Unlike the other version of this function, day and month names must
+ be given in the user's local language. It is only possible to use the English
+ names if the user's language is English.
+
+ These expressions may be used for the time part of the format string:
+
+ \table
+ \header \i Expression \i Output
+ \row \i h
+ \i the hour without a leading zero (0 to 23 or 1 to 12 if AM/PM display)
+ \row \i hh
+ \i the hour with a leading zero (00 to 23 or 01 to 12 if AM/PM display)
+ \row \i H
+ \i the hour without a leading zero (0 to 23, even with AM/PM display)
+ \row \i HH
+ \i the hour with a leading zero (00 to 23, even with AM/PM display)
+ \row \i m \i the minute without a leading zero (0 to 59)
+ \row \i mm \i the minute with a leading zero (00 to 59)
+ \row \i s \i the second without a leading zero (0 to 59)
+ \row \i ss \i the second with a leading zero (00 to 59)
+ \row \i z \i the milliseconds without leading zeroes (0 to 999)
+ \row \i zzz \i the milliseconds with leading zeroes (000 to 999)
+ \row \i AP or A
+ \i interpret as an AM/PM time. \e AP must be either "AM" or "PM".
+ \row \i ap or a
+ \i Interpret as an AM/PM time. \e ap must be either "am" or "pm".
+ \endtable
+
+ All other input characters will be treated as text. Any sequence
+ of characters that are enclosed in singlequotes will also be
+ treated as text and not be used as an expression.
+
+ \snippet doc/src/snippets/code/src_corelib_tools_qdatetime.cpp 12
+
+ If the format is not satisfied an invalid QDateTime is returned.
+ The expressions that don't have leading zeroes (d, M, h, m, s, z) will be
+ greedy. This means that they will use two digits even if this will
+ put them outside the range and/or leave too few digits for other
+ sections.
+
+ \snippet doc/src/snippets/code/src_corelib_tools_qdatetime.cpp 13
+
+ This could have meant 1 January 00:30.00 but the M will grab
+ two digits.
+
+ For any field that is not represented in the format the following
+ defaults are used:
+
+ \table
+ \header \i Field \i Default value
+ \row \i Year \i 1900
+ \row \i Month \i 1 (January)
+ \row \i Day \i 1
