UTC Time Format Display

This calculator requires the use of Javascript enabled and capable browsers. This creates and displays the UTC time International format, in the guidelines of RFC 1123. This non-standard RFC 1123 was originally posted in October of 1989. Though it was NEVER formally adopted as a standard, this is much more of a standard than the standard that more or less replaces it, ISO 8601. An RFC is a Request For Comments from those that may have reason to influence the request, or have significant input. Below, we further define what we feel is the most bizarre (clearer?) standard we have ever seen in computers.

In order from left to right, with a space between each,

Day in the form of DAY, (Three letter abbreviation followed by a comma)
Date in the form DD-MON-YYYY
Month in the form DD-MON-YYYY (Three letter abbreviation)
Year in the form DD-MON-YYYY

The date and time are displayed on the same line, date first followed by the time, and the time is in this format, with a space between the date's year and the hours,
Hours in the form hh:mm:ss
Minutes hh:mm:ss
Seconds hh:mm:ss

The time is Coordinated Universal Time (UTC), though the indication can optionally be Greenwich Mean Time (GMT).

In contrast to ISO 8601, a standard that is TANS (there ain't no standard), in reality, this is fairly tight! There are however, variations in how UTC is displayed. Click here to see a variation of the display on a site that is nothing short of spectacular. See the Earth based on this UTC time.

For more information on the subject and perhaps a clearer understanding of how non-standard standards really are, you might want to look at these sites: http://www.ietf.org/rfc/rfc1123.txt, http://www.w3.org/TR/NOTE-datetime and http://www.cl.cam.ac.uk/~mgk25/iso-time.html.

The time shown in this display is current UTC, also displayed on the browser information line. The tables shows time zone differences of UTC time to the other zones (As opposed to the zones to UTC. In our tables below, UTC is 11 hours ahead of, or earlier than, Samoa.), and in the USA for both standard and daylight saving time. Daylight time begins in the United States on the first Sunday in April and ends on the last Sunday in October. On the first Sunday in April, clocks are set ahead one hour at 2:00 a.m. local standard time, which becomes 3:00 a.m. local daylight time. On the last Sunday in October, clocks are set back one hour at 2:00 a.m. local daylight time, which becomes 1:00 a.m. local standard time. Not all places in the U.S. observe daylight time. In particular, Arizona, Hawaii, and most of Indiana do not use it. In 2003, daylight time begins on April 6 and ends on October 26. In 2004, daylight time begins on April 4 and ends on October 31. In 2005, daylight time begins on April 3 and ends on October 30.

*Editor's Note: We received *TONS* of E-Mail for not including the lesser known of the US (designated) time zones on our original version. It was our oversight and we apologize for it. Thanks for all of your comments!
