HOUR incompatibility daylight saving time ?

Post by Scissors » 2003 Nov 20, 09:15

I regularly "sync" some folders to a (Novell) server disk. Well, i tend to have the "originals" on a laptop folder, and sync them to the server space quite regularly.
But now going through some sub-folders who should not have been changed, i see that the "hour of last modification" has "become" different ... the dates and minutes match, but the "hours" are 1 hour off ... after the "summer time" switched back to "winter" mode.
What this means is: on the Novell disk, dates/times were left AS-IS, on the (Win2K Pro) laptop the modification dates seem to have changed, but it's NOT a real "file has changed" sign, only "we changed a clock somewhere and Windows tries to indicate the original time in today's timescale".

Is there a workaround to that, because when going through folders where "SOME" files have changed, 2xEplorer will suggest to re-sync EVERYTHING.

Maybe i'll have to dig into Windows settings for it ("don't change file times on already-saved files" won't work, as Windows is merely interpreting the same timestamps with a different mask ... previous-hour-mask+/- 1 )

Someone any idea, or can 2xExplorer compare the actual "timestamp numbers" instead of th "dates shown by windows and Novell resp" ?

I think the same thing would apply if i were syncing to a machine in a country where daylight-savings-time is toggled on a different date?

this is a very big thorn on my side that I haven't managed to pull out
some filesystems store daylight-adjusted times and others don't. You don't know which is which to adjust accordingly

the workaround is to use content syncrhonization Alt+F9 or the special Sync-Touch command that makes the dates identical using the active pane as a guide.

Big thank you

I used the "sync on content" a few times, but it's much slower.
But i already had guessed that it would be a "file system specific item", so i really didn't want to blame anyone.
This mirror-browse / synchronize files is really something MS "just forgot to think about", but you did. Thanks again.

(leaving now, time for lunch, and back to w**k after that)

This anomaly occurs when you copy files from an NTFS file system to FAT-16 or FAT32 (and maybe back again). This 'time-shift' can really be a pain. Some programs allow you to shift the time of the files on one side by one hour (+ or - and more than 1 if you wish??). For an example: see FileSync (www.fileware.com)

Maybe this is an option for X2, Nikos??
Dumb questions are the ones that are never asked :turn:

2x's sync touch does a good job, so it will be ported eventually
