WORLD TIME ZONE ABBREVIATIONS
UTC (Universal Time Coordinated) defines the universal time zone, to
which all the other time zones are relative. UTC is the same as
Greenwich Mean Time (GMT). It observes no Daylight Saving Time
(summer time). UT (Universal Time) is based on the Earth's rotation,
and often used in Astronomy. TAI (International Atomic Time) is
based on atomic clocks. The military of many nations refer to time
zones as letters, for example: Z (Zulu) = Zero Meridian (UTC or
GMT). The other letters / words for different timezones are listed
below. A to M moves eastwards and N to Y moves westwards. The letter
J is skipped because J (Juliet) refers to current local time of the
observer. The International Date Line (the place where a new day /
24 hours starts / ends) is between time zones M and Y. Time zone
common names are also listed, with examples of citys, countries,
areas included in each time zone.

ADJUSTING FOR DAYLIGHT SAVING TIME
Daylight Saving Time (or Summer Time) is a modification of standard
time by advancing clocks by one hour during the summer. This change
makes the sunset and sunrise one hour later than during normal time.
The purpose of this alteration is so that people can enjoy more
daylight in the evening hours (and save power needed for artificial
lighting after dark). Clocks are adjusted one hour ahead when DST
begins in the spring, and moved one hour back to standard time in
the autumn (an easy way to remember this is "spring ahead, fall
back"). So during the months of March or April through
September or October, countries in the northern hemisphere may
observe DST. During the months of September or October through March
or April, countries in the southern hemisphere may observe DST. Some
countries / states observe Daylight Saving Time and others do not.
The chart below will help you adjust for Daylight Saving Time. Read
