The constraints from timezones aren't tight enough to make any diffence to leapseconds. For civil time the key requirement is that everyone agrees, which is why timezones are wider than a second. The situation in Xinjiang is a good example, because the argument over how to set the clocks is entirely political and makes little practical difference to things like business opening hours.
