Military time zones span the area 7.5 degrees on either side of the
meridians, starting with the Prime meridian in Greenwich
(0 degrees). This time zone (UTC) is called Zulu time, since zero
starts with the letter Z.
From Zulu moving east, the time zones are centered on the following
meridians. The time zones do not always run straight on the meridians
with a 15 degree span, since local time zones are also considered.
