/**

Stores dates in universal time and provides parsing of internet style dates 

into TDateTime and RFC 1123 (updates RFC 822) dates.

Supports parsing of the following date formats:

Sun, 06 Nov 1994 08:49:37 GMT  ; RFC 822, updated by RFC 1123

Sunday, 06-Nov-94 08:49:37 GMT ; RFC 850, obsoleted by RFC 1036

Sun Nov  6 08:49:37 1994       ; ANSI C's asctime() format

In case of Date Formats with offsets "Mon, 21 Jan 2002 23:00:00 +0210" , equivalent 

time in UTC can be determined by substracting the offset from the local time (RFC 3339).

All dates are store relative to Universal Time and not local time.
