The sentence above still uses slightly incorrect terminology. UTC is timescale and not a geographical location. There is no such point or a

You're right that UTC is not a geographical location. It is a region in the abstract one-dimensional circular space of time zones, and other time zones are east or west from that region in the space of time zones. Because those time zones map continuously (though not monotonically) to geographical regions, it is correct and useful to use “east” and “west” to describe the relative positions of time zones in the space of time zones, because those two directions map in both spaces the same way.

If you read UTC here as the Greenwich meridian, then the sentence is incorrect because there are places west of Greenwich that use negative offsets.

Don't do that, then :-) UTC is not the same as the Greenwich meridian, and this passage doesn't imply that anywhere, so reading them as identical will lead to incorrect conclusions. http://bugs.python.org/review/8810/diff/5785/Doc/library/datetime.rst#newcod...

It's not quite redundant; it carries the implication that there is no purpose *other than* the informational. I think that's the main point of this sentence (which I didn't write, merely moved). Would you prefer “is only informational”? I think that would be better. http://bugs.python.org/review/8810/diff/5785/Doc/library/datetime.rst#newcod...

Grammar? "it mean" -> "it means" or "for it to mean"

The sentence is correct English grammar, AFAICT; it refers to the action, not the state. “there is no requirement that it mean foo” has the same meaning as “there is no requirement for it to mean foo”, but the former is less clumsy IMO. http://bugs.python.org/review/8810/diff/5785/Doc/library/datetime.rst#newcod...

Checking the source in my tree, yes, it's spurious. That blank line can be deleted without a problem. http://bugs.python.org/review/8810/
