Who managed the time zone?

Time zone are the zone where time is managed especially by the latitude. When I researched them, I find the time zone to be illogical like France and Spain should be Western Europe Time Zone or Malaysia should follow Southeast Asia Time Zone. I was angry that I want to find who managed the time zone.

The thing when I searched, the Internet never gave me an answer, only who founded the time zone. Quora is even less helpful. So who managed the time zone in the world?
