I had this same issue, but found a workaround (At least a temporary one)
Right click the date/time toolbar in the bottom right corner, then click "Adjust date/time" from the menu.
In that menu, scroll down to "related settings" and click "Add clocks for different time zones"
This SHOULD bring up a classic windows menu. Click the far left tab for "Date and Time" and select your time zone there. Click "Okay" and then "Apply" and you should be good to go.
