Additional clocks, how to update them?

[AC Question]

I have an additional clock set for a different country, Uruguay, apart from my home clock. Uruguay used to change to summer timer in October, but from 2015 this has been abolished. However, the time in my phone has automatically changed to summer time. Since this is only an additional clock, it doesn't seem there is an option to change at all. Is this going to be somehow "centrally"updated?
