UniversalTimeToLocal

Convert UTC time to local time

Declaration

Source position: dateutil.inc line 429

function UniversalTimeToLocal(

  UT: TDateTime

):TDateTime;

function UniversalTimeToLocal(

  UT: TDateTime;

  TZOffset: Integer

):TDateTime;

Description

UniversalTimeToLocal converts a universal time indication to a local time: it applies the TZOffset timezone offset to the UT Universal time (UTC). If no TZOffset is specified, the local time offset as returned by GetLocalTimeOffset is used.

Note that for times in the past or in the future, or for timezones with DST, omitting the TZoffset may lead to wrong results, as the current timezone offset is used. Calculation of the correct timezone offset for a given date is very complicated, and outside the scope of this call.
