Windows 7: System Time Falls Back 1 Hour

System Time Falls Back 1 Hour

I'm running Windows 7 Ultimate on an HP 580T with 12 Gigs of RAM.

For about a week now, I'm noticing the system time keeps falling back one hour.

When it was time to "spring ahead" one hour, the clock updated as it should. But Im noticing during the last week or so that the time has fallen back one hour.

I've gone to the change date and time settings and corrected the time but within a few hours, it falls back again.

When I go to the BIOS, the system clock has the correct time so I'm guessing it is something in Windows.

The steps I've taken are:

Virus scan in safe mode: negative results.
Malware scan in safe mode: negative results.

Windows updates are current.
I've disabled synchronization with a network time server.

You don't realize how important the correct time is on you computer until it is wrong!

Any suggestions?

Could be a broken CMOS Battery try replacing that.

It might be the CMOS battery, but then the BIOS time should be wrong.

Try disabling:
- automatically update time from a server ("internet time" / "synchronization")
- automatically adjust time for daylight savings

The settings are spread around various places in "timedate.cpl" (control panel).

See Time Zone - Change and ensure that you have checked the option Automatically adjust clock for Daylight Saving Time.

The time in the BIOS is correct. In fact, so is the date. If it was the battery, I'd guess the time in the bios would be wrong.

- I've disabled time server sync prior to this post, but the problem still exists.

- Currently, the automatic adjust for daylight savings is checked. I will try to uncheck it and see what happens.

Have you set the correct time zone?

It's been two days since I unchecked the automatic DST and the problem seems to be "resolved". But the trouble is that i want the computer to automatically adjust for DST. So, now knowing that the problem is related to DST, what would cause the computer to keep "falling back" when it shouldn't do so until November?

Sorry to say that I just sat down at my computer today and even with DST update box unchecked, the time has fallen back one hour. I'm in NY Eastern time zone.

I'm wondering if I picked up a virus or malware which is causing this problem....
