There are Only Two Timezones

I mean, think about it. Almost every timezone in the world can be described as UTC+OFFSET, where OFFSET is a positive or negative number of hours and minutes.

There is only one exception: Universal Greeting Time.

Universal Greeting Time

Universal Greeting Time is the convention of greeting people in online chat with "good morning" regardless of the local time of day of either person.

=> IndieWeb article.

[Universal Greeting Time] states that it is always morning when person comes into a channel, and it is always late night when person leaves.

=> The original (I think) definition.

So. Errh. QED?
