System Time Falls Back 1 Hour

Here's an SF thread i found about a similar issue.
The last post in this thread has something you might try to reset Time sync...

System Time Service

I know that there have been many causes of the problem I described here. HP insisted that it was the mother board as changing the CMOS battery didn't resolve the issue. Personally, I didn't think it was the CMOS battery as the date and time was always correct even though it was incorrectly displayed in the task bar.

They wanted to send me a box with a return label to send it back for warranty repair; they were very slick. You see, I have an on site warranty where the technician is supposed to come to my home. It was only after I pointed that out that they offered to send someone.

I decided I would reinstall the OS. I really believed it was something I picked up off the web. Apparently, I was right as I've done a fresh install and the time has been true for a week.

Thank you to all that pitched in to help.

Hi


I am writing from Slovenia, I've had a similar problem with win7 time syncing for years, one different machines and different distros (premium, home, pro, ...). The problem arises after a new install on a computer, but randomly - as in after some installs time sync works as should, sometimes it does not.

This is a trick I've found to eliminate the problem:

First time sync without automatic DST. After time is synced accordingly (no DST shift), turn on DST.
If done like this time was always synced properly, as stated, otherwise it was a gamble.
After I found this trick I tried a couple of times using different time zones for the first sync. It also didn't seem to produce the problem.

GMT + 1 (Ljubljana) here was usually exactly 2 hours late, if problems did rise up. Anyways, it is always an exact shift (1, 2, 3 hours), never just some random time.

Same thing, I'm also in the same region as Dolinko (CET+1, Prague). Turning off Daylight Saving Time helped but I also had to use a different server. Either servers "tick.usno.navy.mil" or "128.105.37.11" worked for me (you can add more servers in registry HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersio n\DateTime\Servers). The other ones, not so much. Again, I'm not sure how permanent this solution is and there's also DST change next week in Europe so I'll be monitoring this.

Just started on my pc this morning, an hour early. Bios clock okay. Corrected the clock and did an update on windows time server and immediately went back again. And yes, Time zone and everything is correct, it just started happening. Turned off the time service and its ok after reboot, so something with their servers?

Had to add 2 MS updates to correct daylight savings time hours

i have the same problem.

Downloaded KB2794119 and KB3162835, altho I think I only needed the second one.

i downloaded and installed these kb files.None of them works.my clock lags behind 1,2,3,4,5,6 hours.
