Windows can display up to three additional clocks and time in other time zones. Viewing can be done by hovering or pointing to the taskbars clock.
Lets dig into the topic from Windows to registry.
To add, click ‘Change date and time settings…’ and configure those clocks located at additional Clocks Tab. For each clock, click to check ‘Show this clock’. Select a time zone from the drop-down list, type a name up to 15 characters, and then click OK.
