What is the file TIMESTAMP precision

[Guest]

What is the precision of the internally stored file timestamp? I can decode
it to integer seconds (Compac FORTRAN library routine) but "thought" it was
actually stored to a higher precision than that.

Thanks - Greg

I seen to recall reading that it was stored as a count of 100 nanosecond intervals since January 01, 1601,
but I could be thinking of something else.

AFAIK, That is true for a NTFS file system, but a FAT/FAT-32 file
system has a precision of 2 seconds.
