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:
http://developer.apple.com/mac/library/DOCUMENTATION/Carbon/Reference/File_Manager/Reference/reference.html 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.
