"UTC" Time

At 6:04 PM (1804) the sea buoy off Sunset Beach, NC - near the SC/NC state line - had this to say:

"Station 41024
CaroCOOPS
Location: 33.848N 78.489W
Conditions as of:
Fri, 26 Aug 2011 20:00:00 UTC"

Does any one know what is "UTC" time??
Thanks,
Capt'n Bill

Sometimes also called Zulu time or GMT time it the time at the Greenewich Mean Line.Note the 1804 and then the UTC of 2000.Its just a standard time to keep everyone on same time scale. Pilot navs or Military its used exclusivly.

Makes sense! Thanks!

Probably more than you wanted to know:

Coordinated Universal Time (abbreviated UTC)[1] is the primary time standard by which the world regulates clocks and time. Computer servers, online services and other entities that rely on having a universally accepted time use UTC for that purpose.

Coordinated Universal Time is a time standard based on International Atomic Time (TAI) with leap seconds added at irregular intervals to synchronize with the Earth's rotation.[2]

UTC is conceptually different from Universal Time and Greenwich Mean Time (GMT), but it can be used interchangeably where sub-second precision is not required.

Time zones around the world can be expressed as positive or negative offsets from UTC as in this list.

All the above names have been dropped, but remembered by us old folk. U.C.T. time, stands for Universal Coordinated Time. Time starts at Greenwich Mean line, England. I always used Zulu time before. Most of Florida is 5 hours behind. 12:00am UCT is 5:00 AM in Florida. You add 5 hours to the UCT time for the eastern time zone.

For Eastern Daylight Time (EDT) subtract 4 hours from Zulu time. When it becomes Eastern Standard Time (EST) subtract 5 hours. Ireland is Zulu plus 1 hour. Zulu time gets shortened to "Z" in conversation. 12Z is 8AM on EDT.

Note that the time in Greenwich England is not UTC time during the summer, as noted with Ireland they leap forward an hour like us.
