Code:

Define.i DateMod
Define FilePathName$ = "c:\TRY_PB_SetFileDate.txt"
If CreateFile(0, FilePathName$)
  CloseFile(0)
  DateMod = ParseDate("%yy-%mm-%dd %hh:%ii:%ss", "12-01-02 00:01:01")
  Debug FormatDate("%yy-%mm-%dd %hh:%ii:%ss", DateMod)
  Debug SetFileDate(FilePathName$, #PB_Date_Created, DateMod)
  Debug SetFileDate(FilePathName$, #PB_Date_Modified, DateMod)
  Debug SetFileDate(FilePathName$, #PB_Date_Accessed, DateMod)
  Debug FormatDate("%yy-%mm-%dd %hh:%ii:%ss", GetFileDate(FilePathName$, #PB_Date_Modified))
EndIf

But I get Sunday, ‎January ‎01, ‎2012, ‏‎11:01:01 PM for Windows 7 properties of the file.

Should I use the Windows API or am I doing something wrong with regard to daylight savings time or is this a bug?

I know DirectoryEntryDate(iDir,#PB_Date_Modified) retrieves a valid and accurate Date since I stored it and wrote it back to a file in a different location using SetFileDate() and they were identical.

Skywalk,

I have the same result as you, Windows Explorer shows one hour earlier than your ParseDate().
As I am living in a time zone GMT+1 (or UTC+1), I thought first that Windows showed the UTC time (Universal Time Coordinated).
BUT... I changed the time zone to UTC+9 (=Japan), and the Explorer was showing the same time as the ParseDate().

I am also puzzled.....

Perhaps it has something to do with day light saving setting, just a thought. :idea:

When I use a date and time that is inside the day light savings time period, as we are now, 3/11/2012, 03:00:00, it works correctly.

If I use a date and time just prior to 3/11/2012, 02:00:00, I lose an hour. This must be for daylight saving, and appears correct?

Since technically 3/11/2012, 02:30:00 does not exist, my system still removes an hour, though right-clicking on the file seems to show some screwy settings when you try to use this invalid time.

Not sure, but this topic can probably guide you to find the reason...
