Windows 10: Wrong time switching to correct on wakeup

When I wake my Windows 10 anniversary version from sleep, frequently (not always) the time that appears is several hours off and then without my doing anything it quickly switches to the correct time.

Is this normal? Could it be an early warning about my cmos battery?

Thanks.

Time appears incorrectly (correct time but wrong appearance)

Hey y'all.

This morning I had a severe problem on booting of my computer and after several minutes it got to function properly. Now, while the date appears normal as it should (13.02.18.), the time appears somewhat unusual (example: 10:39am appears as
N\4PV. Here is even proof below:





How do I fix this issue? When I open the calendar the long time appears properly, and even the short time appears normally when I insert a timestamp on Notepad (F5).

Any help is appreciated.

Hi,

This can happen if the Taskbar was not refreshed for a long time. To resolve your concern, we recommend that you reset the Taskbar by following the steps below:

• Press CTRL + SHIFT + ESC key to open Task Manager.
• On the Processes tab, look for Windows Explorer.
• Right-click Windows Explorer, then click Restart.
• Wait for File Explorer to restart and see if Taskbar starts working again. Let us know if this method works for you.

Refreshing the taskbar from time to time will prevent encountering this type of issue moving forward.



Get back to us if you need further assistance.

 

Gosh, yes it could be a CMOS warning sign. Your date&time widget is probably contacting a designated time server sometime after startup/wakeup, and correcting the erroneous system time value. The simplest explanation for that discrepancy is indeed a failing or underpowered/performing CMOS battery.

Thank you. I will quickly read how to backup the cmos settings and then how to change the battery.
