I routinely set my Windows system time to a fake date/time to create files with specific timestamps.

  • For example, suppose the calendar date is 4/1/2012 but I want a file to be created on 3/1/2012, I will set the Windows system date to 3/1/2012 before creating the file.

Now I need to determine the true calendar date that a specific file was created on. Is this possible?

You cannot have your cake and eat it too. The system only knows the time it is told. – uSlackr Apr 4 '12 at 1:10
You know you can just set the file creation time without having to change the clock. Any number of tools exist to do this. – David Schwartz Apr 4 '12 at 2:38

No. You told the computer what the current time was, whether that was correct or not. The computer assumes the clock is the real time and doesn't know of any other time.
