Hi Brent,

That might be a good approach. I did something like that with the
TimeZoneDatabase tables, such that the current time zone is a proxy
that points to the Olsen time zone tables, and "DateAndTime
localTimeZone offset" finds the proper offset in the tables. This
works well.

Having said that, I think that Chris' original idea was to use only
the UTC-based (#globalize) style, and to rely on idioms like
"DateAndTime now asDate" to create an instance of Date with an
offset for local time zone. Having played around with the inbox changes
a bit now, I have to say that I think Chris was right, it's is probably
better to keep things simple and consistent, and not try to have a
#localize variant.

Do you (Brent) have a preference on this? For myself, I'm happy
with Chris' proposal (minus the #localize feature, which I suspect
that Chris will be more than happy to remove ;)
