Hello community!

I have Windows installed on multiple devices, including external Disks. I often find that when I boot (even from internal disk), the system time is reset to GMT instead of my locale time. Everytime that happens (and it doesn't always happen), I have to right click the date and time on taskbar, choose adjust date and time and then manually run the sync service in that Settings page.

I have tried changing the Windows Time Service (under Services) to Automatically Start (I think it is Automatic (Delayed) by default), but that hasn't helped.

How do I fix this?

Change CMOS battery
The CMOS battery is long gone (some 4 years back). A 'professional' broke it when he opened to service it.

But I think the CMOS battery is no longer relevant. Because I see that as long as main battery doesn't run out, the system time is intact. This problem doesn't happen always as mentioned in OP.

Yes. That's when I decided I will service my laptop myself. Ever since I made that decision, my experience has been much better and I have learnt a lot too.

The CMOS Battery is the battery that holds the memory for the clock and calendar, not the actual laptop battery. :) I'm curious, what date does it reset to? January 1, 2000? lol

Remove the battery and drain all the power by holding down the power button.
Now plug the laptop into a wall socket. Do not put the battery back in.
Restart the laptop. What time does it say it is ?
Is it correct ?
If not you do indeed need a new CMOS battery.

It is only the time that gets reset, not the date (even though the date can be a day behind depending on my locale time).

As far as I know, the CMOS battery is irrelevant today since the system uses location to automatically update the date and time during boot. Same holds true for calendar since all information would be automatically synced.

Yes, it is a laptop. If CMOS battery was required, then as mentioned by @JMedlock83 , the date would be reset too. That isn't happening.

CMOS battery is irrelevant today. I'm not sure if modern laptops come with one even.

Please note that this problem happens randomly. Sometimes it is off when I do a simple restart. Other times, it is correct even if I boot my laptop after a few days.
