Windows 10: Time zones change in sleep mode

Every time I put my PC into Sleep mode, when I wake it, it switches from Eastern to Pacific. When I go to the system settings, the time zones is greyed out, so I have to go to the command center to switch back the time zone. I went into power shell last night, but that didn't seem to save.

Unable to change the time zone in Windows 10

I'm running Windows 10 Pro. My time zone is Jerusalem, but I need to change it to Eastern to test a program I'm working on.

The time zone won't change. I have tried:

• From the clock/calendar, when I change it - it changes back.
  
• From Control Panel - Date and Time, "Change time zone..." - when I click save I get the message "Error occurred - your changes could not be saved."
  
• As the Built-in Administrator from the command line using tzutil - I get the message "Insufficient privileges to set the current time zone."
  

The registry key TimeZoneInformation has Full Control for Administrators

Administrators are listed in the Local Security Setting "Change the Time Zone"

Any suggestions?

 

Time Zones do not change

Hi Andre,

Thanks for taking the time to help. I appreciate it.

I opened the account on my computer which has Administrator Privileges and ran regedit.

In the first string you suggested, it was already set to NTP.

In the second string, I changed the value to 3, as instructed.

Regrettably, after the restart - the trouble is still present. The Time Zone is still stuck on the time zone of the place I started my trip from.

I opened Settings>Time and confirmed that the toggle is set to Automatically Detect/Change the Time Zone, but it clearly isn't working. Additionally, the place where it displays the Time Zone (which if you click on usually drops down a list where you can
select a new TZ) is grayed out and not longer drops down a list if you click upon it.

Also grayed out is the toggle allowing you to choose to ignore Daylight Savings.

Hmmm. Puzzling.

 

Time zone won't change

Hello,

I live in Eastern Time zone, and I am trying to change my PC's time zone to this time zone. However, every time I restart of wake the PC from sleep, my time zone reverts back to IST time zone. How do I change it permanently?
