- you mean the offset right?
https://en.wikipedia.org/wiki/ISO_8601#Time_zone_designators says that "±hhmm" is valid too in iso8601
so i think the bug is more in Time because the offset should be valid?
Time itself does print it a... -

07:35 AM Feature #14788: `Hash#keys` Could Accept a Block
- If I were you, I would rather request a new method named `Hash#select_keys` for that purpose.

From `keys {|k| k.something }` I wouldn't know what it does with the keys, if they would select or map the keys or both.
Is probably against that "least surprise" thing -

It also does not work in "block-like" places like a for loop. So this is not valid syntax:
