I've noticed in Delphi XE that TTimeZone.Local.ToUniversalTime is a week
out on daylight savings, it works correctly in XE5 however (and probably
earlier versions).
program Project6;
{$APPTYPE CONSOLE}
uses
SysUtils,
DateUtils;
begin
Writeln(DateTimeToStr(TTimeZone.Local.ToUniversalTime(StrToDateTime(
'5/4/2014 2pm'))));
Writeln(DateTimeToStr(TTimeZone.Local.ToUniversalTime(StrToDateTime(
'12/4/2014 2pm'))));
Readln;
end.
Outputs
5/04/2014 1:00:00 a.m.
6/04/2014 1:00:00 a.m.
in XE (incorrectly) and
5/04/2014 1:00:00 a.m.
6/04/2014 2:00:00 a.m.
in XE5 (correctly). XE works correctly from the 13th onwards - so it's
just a problem for a week.
Does anyone have some code that does conversions to UTC correctly for
Delphi XE?
