What's missing the mark, no leading 0 on the hour, or the extra 0 hour
specification?

Yes, unfortunately it looks like manual extraction is your only option
for that.  I'd support an RFE for a strftime-like __format__ method on
timedelta that only supported certain %-codes, though.  I haven't
checked to see if there's already an open issue.
