If I'm understanding the question, I don't believe that's possible. Time is relative to the computer location, not the user location. Thus, if you have a computer in China and a user in the UK, the user in the UK will (should) see UK time on their local PC, but will see China time if they RDP to the computer in China.
Time sync is usually done via GMT/UCT, and then the offset of the local computer is applied to that to get the local time. If the PC in the UK was a member of the domain in China, standard A-D time sync should work and keep the clocks aligned, yet display the respective local time.
