Is there a simple, 2-3 line way to do this?

Look at the clock man page, especially where it mentions the -gmt option to "clock format".


That will *format* the number of seconds I have as a GMT time. But the number of seconds I have isn't GMT, it's local. Given the local time, I want to know the GMT time.

The only difference in time between here (pick your own definition for "here) and GMT is the formatting, so I'm not sure what you're asking.

How is what I suggested not what you want? Does the following code print something that is unexpected for you?

  % set now [clock seconds]
  1135889846
  % clock format $now
  Thu Dec 29 14:57:26 -0600 2005
  % clock format $now -gmt 1
  Thu Dec 29 20:57:26 +0000 2005
.
