Dear All,
Can anyone clarify American and European time zones for me? I am trying
to write instructions for setting up a dial which can be used in any
location.
The NASS dialist's companion gives the meridians for US time zones
as: Atlantic 60° W
Eastern 75° W
Central 90°W

The time zone boundaries in North America are quite irregular. Have a look at

maps.

Hello Harriet,
The reference meridian is 75W for EST, and here in Cincinnati (approx 84W30)
we are about 38 minutes behind the clock for local noon. At certain times
of the year the difference between unadjusted dial time and watch time can
be almost an hour! The official time zone lines weave
Hi Fernando (and All),
This time of year, when DST arrives,I always harken back
to my design school days. We always seemed to have way too much work to do
for the time alotted, time consuming work such as full color renderings

Hello!
A few days ago I sent a brief story about watching an eclipse with
school children. If anyone is interested, it was on 1977 October 12. I

Your U.S. Time Zone designations are correct, but the boundaries are
determined politically, not strictly by latitude, and are subject to
change. For example, time in Indiana is determined by county, and a
redetermination was recently considered. However, I would think (probably

Hi All,
It seems that some states do not need Daylight Savings Time as much as some
of us. This is because of their natural location in the western portion of
their time zone. Arizona is in natural DST all of the year. Take Phoenix,

Hi Gordon (and All),
I was not aware that Indiana determined time by county, and we have lots of
guys from Indiana who work here at FX. They did not even know that!
This discussion leads me to the next logical question for a diallist trying
to design a compensated sundial for someone far away

If you go to mapblast.com and enter the address of the place,

By the way, does anyone else still use a pocket calculator for sundial

Hello All,
How about following nature and just changing the hours we
conduct our business in, instead of the clocks? Would people be more upset by
the idea of having lunch at 10:00, than having a two hour time shift and
lunching at midday?
best wishes,
Sarah

If we wish a zoneless time then let's continue to use UTC, successor to
GMT, with its bases 24 and 60. These have been around a lot longer than the
Swatch.

a modest proposalas an alternative. Why doesn't Swatch produce a watch
that shows local solar time. How often have you been frustrated trying to
explain why high noon is at 1:41:30 pm clock time. Think how useful a
solar watch would be in determining which direction is north for

think of the latest zoneless time concept, Internet Time where the day is broken
up into beats eliminating the need for geographical based time zones. Is it seen
as helping to make ours one world or as cynical "commercial"
exploitation?
