Thank you Pam. What is the difference between local and zulu, and what is zulu time?

It's time to runaway if there's thousands of 'em!

Apart from the reasonable answer above which i have to say is exactly what i would do if faced with that lot

From Google .just to make it simpler to type this is the american navy way of putting it.

What is "Zulu" time?
"Zulu" time is that which is more commonly know as "GMT" (Greenwich Mean Time). Our natural concept of time is linked to the rotation of the earth and we define the length of the day as the 24 hours it takes (on average) the earth to spin once on its axis.

As time pieces became more accurate and communication became global, there needed to be a point from which all other world times were based. Since Great Britain was the world's foremost maritime power when the concept of latitude and longitude came to be, the starting point for designating longitude was the "prime meridian" which is zero degrees and runs through the Royal Greenwich Observatory, in Greenwich, England.

When the concept of time zones was introduced, the "starting" point for calculating the different time zones was agreed to be the Royal Greenwich Observatory.

Unfortunately the Earth does not rotate at exactly a constant rate. Due to various scientific reasons and increased accuracy in measuring the earth's rotation, a new timescale, called Coordinated Universal Time (UTC), has been adopted and replaces the term GMT.

The Navy, as well as civil aviation, uses the letter "Z" (phonetically "Zulu") to refer to the time at the prime meridian.

NOAA satellites use Zulu Time or Coordinated Universal Time (UTC) as their time reference. The satellite images that appear on NOAA's Web sites are stamped in Zulu time.

The Department of the Navy serves as the United States official timekeeper, with the Master Clock facility at the U.S. Naval Observatory, Washington, D.C.

Edit to fix Mayfly's BOBO (runs & hides

Zulu is GMT
Local is currently BST, i.e. Zulu +1hr - simples....

By the way, Mayfly, HRH isn't really the correct address for Her Majesty the Queen, - but I don't suppose she spends a lot of time on Iconic anyway so she probably won't notice..... B-)
