It's been a while since I looked at it, but my recollection is that
much of the standard date/time math which people assert can't handle
practical use cases do work if the timestamps and times WITH TIME
ZONE have a time zone in the offset-from-UTC format. I have yet to
see anyone provide an example where this isn't true; if anyone has
such an example, it would be instructive to see it.
