24hour GMT
Date changes each time
hour hand passes midnight
(24:00 hours)
When setting Date and
GMT
, the minute and hour hands must
not
be positioned between
8PM (20:00) and 3AM (03:00). During this time the date mechanism is engaged and
adjusting it may cause damage to the gear.
GMT
(Greenwich Median Time) is an international time standard originally established to facilitate oceanic navigation
and is based on the time in Greenwich, England from which the remaining 23 global time zones are derived.
GMT
is
5
hours ahead of
Eastern Standard Time
(
EST
) and
4
hours ahead of
(
EDT
) during
Daylight Savings Time. So if the time is
0900 GMT
, it is 4:00AM in New York City and 1:00AM in Los Angeles during
Eastern Standard Time
(
EST
), but during
Eastern Daylight Time
(
EDT
) it is 5:00AM in New York City and 2:00AM in
Los Angeles.
GMT
is also referred to as Coordinated Universal Time (
UTC
) or Zulu Time (
Z
).
