The other reason for doing so is that unix stores internally all dates as UTC, including the dates used in the file system.

Delphi exposes the FileTimeToLocalFileTime API call to get the local time. The fpc unix implementation uses LocalToEpoch (unixutil.pp) which has the folloxing comments: { Transforms local time (year,month,day,hour,minutes,second) to Epoch time (seconds since 00:00, january 1 1970, corrected for local time zone) } I guess fpc wants to be Delphi compatible as much as possible.

Is this correct? I would not expect a difference of 2 hours (the deference from UTC).
