Sorry, must've been seeing things when I wrote EST. Complicated by
the 'EDT' displayed by tzsetup not[?], afaik, being an actual formal timezone
but just a marker as to the current state of the actual EST5EDT timezone.

I use NTP, UTC CMOS (no /etc/wall_cmos_clock), and /etc/localtime copied in.

1) EST - is UTC-5 all year round, and is in use in only a few
geographical places.
2) EST5EDT - is EST (UTC-5) in the 'winter', and 'EDT' (UTC-4) in the
'summer' (now, daylight savings time).

It might be a useful idea, with the current state alongside for
daylight savings zones.

I don't know what the difference is between the 'New_York' and 'EST5EDT'
files. I suppose I could look at the zone compiler for that.
The more formal 'EST5EDT' seems to work fine for me.
