How to? Compare file timestamps accross different file systems...

[mathewsdw]

I am using @FileAge to compare file time stamps where the files are on different file systems. NTFS volume time stamps have a 100 nanosecond resolution whereas a FAT file system has a 2 second resolution. How do I go about converting an NTFS file age to a 2 second resolution value?

It seems a standard rounding computation is doing the trick:

%@eval[ ( %@fileage[file] \ 20000000 ) * 20000000 ]

(20000000 = 2s / 100ns)
(tested with a FAT diskette)
