What? How does it assume it's in local time? It assumes it has
received the value you want decoded. The value 40850.5 treated as a
TDateTime is 03 NOV 2011 @ 12:00.
How do you get the starting date and time of the epoch?
According to Delphi help a TDateTime of 0.0 represents 12/30/1899 12:00
am, while Wikipedia states "start counting the seconds from the Unix
epoch of 1970-01-01T00:00:00 UTC".
You are aware that the definition of TDateTime and that of the Unix
timestamp are not supposed to be the same? The original TDateTime
definiton (Delphi 1 and maybe also 2) started from 01/01/0001 and was
later changed to todays 12/30/1899 to be COM compatible.
And still: It does not matter whether we are talking about local or UTC
time here.

Sven
