Zitat:
Timestamps are updated at various times and for various reasons. The only guarantee about a file timestamp is that the file time is correctly reflected when the
handle that makes the change is closed.
Not all file systems can record creation and last
access times, and not all file systems record them in the same manner. For example, the resolution of create time on FAT is 10 milliseconds, while write time has a resolution of 2 seconds and
access time has a resolution of 1 day, so it is really the
access date. The NTFS file system delays updates to the last
access time for a file by up to 1 hour after the last
access.
Eigentlich sollten 15 Minuten bei List Write ausreichen für FAT und NTFS. Geschlossen wird die Datei auch. Entsprechend könnte es noch sein, das das setzen der Last * Times abgeschaltet wurde. Das ist bei NTFS ein beliebter "Tuning Trick".
