If you look at the file properties in Explorer, the time is an hour longer than specified.

Code: Select all

Date.q = Date(2010, 4, 8, 2, 0, 0)
File.s = GetTemporaryDirectory()+"Test.txt"
CreateFile(0, File)
CloseFile(0)
SetFileDate(File, #PB_Date_Created, Date)
Debug FormatDate("%yyyy/%mm/%dd    %hh:%ii:%ss", Date)
Debug FormatDate("%yyyy/%mm/%dd    %hh:%ii:%ss", GetFileDate(File, #PB_Date_Created))

When you use an absolute date, there is no timezone info in it. As you can see GetFileDate(File, #PB_Date_Created) returns 1270692000 which is the correct EPOCH time for Apr 08 02:00:00 2010. Explorer probably display the time using the current timezone, that's why it's different.
