THIS IS A SUBJECT THAT INTERESTS ME;
I'LL MAKE THIS INFO AVAILABLE FOR
OTHERS WHO ARE INTERESTED.
Time zones are a way of organizing time so that people living
in a large area (country, part of continent) share the same time, just to make
things easy. People living at about the same longitude usually have about the
same local time. There are 25 standard time zones around the world, these are
all an integer offset of hours to UTC-time, for example, +5
hours or -10 hours to UTC. If UTC-time is 12:00 (Noon/PM), then people having
offset +5 hours, have local time 17:00 (or 5:00 PM).
Then... there are some
countries/places not using the standard time zones, they might be 5 hours and 45
minutes ahead of UTC, like Kathmandu
is or some other non-integer offset of hours.
This shows the UTC-time used for calculation of the
World Clock table. UTC means Universal Time, Coordinated, and all the other
cities are an offset added/subtracted to/from this, e.g. 5 hours ahead of UTC.
The time shown here may be some seconds off real UTC-time, so you should
consider other sources to get 100 % precise time to the second.
Daylight Saving Time (DST)
Cities with "*" after the name in World Clock are observing DST at the moment. For more
information about DST please go here.
I retrieved this information from Time and Date.com;
You can create your own personal time clock and keep track of
international time zones on that site. The site is informative and fun!
