Assuming that these figures come from stat (man -S 2 stat for details), it 
should be in something called st_birthtime.  st_atime refers to the last time 
the file was accessed. So, either call stat yourself or, better perhaps, go via 
the file manager:

I would also fire up Windows to see what values it reports for the file(s) in 
question.  Note that viewing the properties for a file in Windows Explorer 
updates the last access time (!).  Like HFS, file dates on NTFS volumes are 
stored in UTC.  These are converted to local time by the Finder / Windows 
Explorer before display but I observe some differences depending on the date 
being reported (i.e. whether or not DST was in effect on that date).

Looking at a few of my own files (on Windows), the creation date doesn't seem 
to be very reliable.  I have several files where it post-dates the last 
modification date.

Subject: Re: getting file creation date from NTFS


      As suggested by Ken, I tried FSMegaInfo on NOTEPAD.EXE in a bootcamp 
volume:
      if I compared it with Finder's display, Finder listed March 30, 2010 
6:48PM as 'Created'
      looks like, st_atime is the creation date?


      'NOTEPAD.EXE'
          st_dev     = 0x0e000003 (major=14, minor=3, disk0s3)
          st_ino     = 2469
          st_mode    = 0x000081ed (-rwxr-xr-x)
          st_nlink   = 1
          st_uid     = 501 (user1)
          st_gid     = 20 (staff)
          st_rdev    = 0x00000000 (major=0, minor=0, console)
          st_atime   = 1269957274.686875000 (Tue Mar 30 13:54:34 2010)
          st_mtime   = 1091595416.0 (Wed Aug  4 04:56:56 2004)
          st_ctime   = 1274540319.708286000 (Sat May 22 14:58:39 2010)
          st_size    = 69120 (67 KB)
          st_blocks  = 136
          st_blksize = 33554432
          st_flags   = 0x00000000
          st_gen     = 0

        It does.
