I am afraid there is no concept of "main guy" there. I raised a similar issue in this list recently. My constraints were a bit different (I wanted to have at least one distinct zone per country) but I also needed a way to find out which was the "main" zone, given a set of zones that have equivalent behaviour if historic data is not relevant. You can have a look at that thread in the list archives (https://lists.iana.org/hyperkitty/list/[email protected]/thread/RDI2IRJBQZWQHKVPLJP4I6EWBV6TY2FO/). The result of that discussion was that a reasonable approach would be to sort each set of equivalent time zones by population, and take the one with the most population as the "main one" in the group. This was useful advice, but I am not 100% convinced this is the way I want to go, so I am still investigating options. Best regards, Guillermo Rodriguez Garcia [email protected]
