View Full Version : Daylight saving and change in backup file timestamp

05-04-2010, 03:17 PM
I regularly synchronise (backup) my PC's hard drive to an external hard drive.

I just went to perform a back up of my most recent file changes and noticed that since NZ turned the clock back one hour in the weekend, to return to NZ Standard Time, that all the files on my backup drive are still showing an hour later than the same files on my PC.

This means my Backup programme is detecting that every backup file has changed and it wants to perform a complete backup, not just my usual incremental backup.

Is there an easy way for my external hard drive files to have their timestamp turned back one hour to coinicide with the timestamp of the files on my PC?

I have seen utilities for this sort of thing, but can't offer any links, sorry.
Google is your friend. :)

FWIW Linux stores all timestamps in UTC to avoid problems like this.
