I am a little confused in figuring out the time expressed in ZULU. If a contest runs from 1400Z to 2300Z what is the actual LOCAL time for people in California? Or in the NY area?

go to   'alphaclock'
download   the  digital clock to your computer.
set for    UTC or  GMT or  Zulu..  al lthe same.

set the colour you like.
You may get a  'cant load all files' message.  but
it extracted the clock and it  shows up on the top line of your screen
;..
check to  start on  boot up etc.
drag it to the left a few inches or it covers up the  minimize and cancel  blocks.

its not straight forward loading as  aclock  has lots of different   downloads.
the clock was down the list a bout  3 or 4 .

Zululand is below Swaziland so Zulu time is 9 hours ahead of California

Does that mean Swazi time is one hour earlier or later than Zulu time?

Zulu time is also called Greenwich Mean Time (GMT) or Universal Coordinated Time (UTC).

Since none of the smart-alec replies actually answered the question...

Look here for a UTC-to-local-time conversion chart for U.S. time zones:
http://weatherarc.com/utc-time-conversion

And here's a world-wide on-line UTC conversion tool:
http://www.timezoneconverter.com/cgi-bin/tzc.tzc

If you use a contest-logging computer program, it usually will contain a provision to tell it your local time zone, and it will convert the time-and.date to UTC (ZULU) automatically.

UTC=Coordinated Universal Time or Tems Universel Coordonne'. The French got involved.

It's odd you mentioned this, I sent an email to my ARES/RACES group and mentioned LOCAL time by using 'L' (which is actually LIMA - Solomon Islands). I knew; but we use L for 'Local time' in the group, but it sometimes causes confusion amongst the veterans.

A station sent me these links:
http://www.worldtimezone.com/utc/utc+1100.html
http://www.labri.fr/perso/strandh/Teaching/USI/Common/Fileutils/fileutils_20.html

In military time, time zones are referenced by a NATO Phonetic Letter.

Hope it helps.

There is a Hamclock program that you can run on your desktop in zulu time. Then you never have to worry again.
