Run the update. In sys-libs/timezone-data-2011n been corrected translation of timezones.
If you do not help, then run in the console <>

where choose my city for timezone?

Edit /etc/timezone file. Zone names like in /usr/share/zoneinfo/ directory, like Europe/Moscow, Brazil/East, Iran or something else.

Then exec this command:

cl-template -l all --merge openrc

This will update /etc/localtime with new settings.
