Hi,
Thank you for posting your query in Microsoft Community.
I understand your concern, and we in Community will try to help you in the best possible way we can.
I suggest you to change the time zone and then change the time, date and check.
How to Change the Time Zone in Surface tablet
* From the “Start” screen, swipe in from the right edge of the screen to bring Charms Bar.
* Tap Setting > More PC setting > General.
* In the right pane, set your time zone to correct under the Time option. To adjust for daylight saving time automatically, turn it ON.
Go to the Desktop screen, touch or click where the time and date are displayed in the lower right hand corner of the taskbar. This should bring up a clock and calendar with 'Change Date and Time settings' at the bottom, touch or click that, change the settings, click or touch OK.
Hope the information helps, if you have any further queries, feel free to post. We are here to assist you.
Regards,
Guru Kiran
