Anyone want to tell me what the %E* modifier is supposed to do for
stftime?
And do we need it? How about the %O* modifier? Is implementing that
important?

Basically, yes.
Just like leap years, but there is no rule (there is no exact
calculations
for it).
Some (rarely) days will have one 0-60 seconds minute (instead of 0-59).

It's ok, Date::Set::Timezone already has 'local time' support (now I
know
it is called 'floating')
UTC times have a timezone

No, these would have to be either:
