Makes sense. I can't see any other real explanation for -7200 value if
I am in +2 UTC timezone.

I believe the correct convention is "Return timedelta...". Another
concern - if UTC is 0 reference point then there is no reason to add
something to it - you just can say - "Return timedelta equal to local
UTC offset."
