Maybe you haven't experienced it yet but it's not as simple. I live in different countries and regularly have to deal with this. There's often confusion about time zones. Sure, it's "just a simple" conversion in theory but firstly the point is that ideally you should not have to do this at all and secondly no one calls it "UTC-6". You're lucky if they add a time zone at all, and when they do it's usually "EST", "Beijing time", "Eastern" (which can be Australian, American or whatever, your job to know from context), etc. Then you have to deal with DST, but only in some countries during some parts of the year. And don't forget the countries that add half hours, or Nepal which is extra special with an additional 3/4 because why not. It's utter madness. Unless you're a savant who can remember all regions with corresponding time zones and all the exceptions, you'd be looking this up, which is what people normally do.
