[Elecraft] Yosemite Sam & zulu time

It used to be Standard Operating Procedure for all hams to keep their logs
in Zulu, (Greenwich) time, in that for working other countries or other time
zones, this is the only practical way to keep QSL card records.

I think it is remiss of current education in ham radio, that we do not
emphasize the continued need for ALL emergency work, and casual operating
records, to be kept, and in Zulu time, just in case we have to document it
at some future time; when we were on the air on a particular date.  Don't
forget the date roll over, if your local date is some zones removed from
GMT.

Perhaps this lax time keeping currently, grew out of the dropping of the
requirement of keeping a log; but I keep one for HF  anyway, "just in case",
and for QSL purposes, and documentation of emergency communications.
Likewise, in working drills for ARES with Red Cross, we keep the Red Cross
log in GMT, to have an unambiguous time reference, and we keep a clock
marked GMT, in the Red Cross shack.  It really helps to use that 24 hour
based system, to know if an emergency message was delivered at midnite or
noon.
