Like New York, London, Sydney etc. I've started by creating this little alias: Code: alias world-clock { var %amsterdam = $time(HH:nn:ss) echo -a 05Amsterdam, NL:07 %amsterdam } But I'm already stuck when I need to calculate another locations time. Does anyone already have something like this? Or what would be a fancy way of making this? Thanks in advance!

For your own timezone you can use $daylight to offset that. Example: Anchorage, Alaska, is GMT -9 hours, plus 1 hour (DST). (GMT -9 +1) = GMT - 8(hours) //echo -a Anchorage, Alaska: $time($calc($gmt - (8 * 60 * 60)),HH:nn:ss)

I now have: Code: alias world-clock { var %gmt = $asctime($calc($gmt - $daylight),HH:nn:ss) var %amsterdam = $time(HH:nn:ss) var %new-york = $asctime($calc($gmt - 14400 - $daylight),HH:nn:ss) echo -a 07 $+ %gmt 05GMT -07 %amsterdam 05Amsterdam-NL -07 %new-york 05New-York-USA. } This returns: 12:45:12 GMT - 14:45:12 Amsterdam-NL - 08:45:12 New-York-USA. Is this the way forward? With daylight savind taken into account? Thanks again

Your times there appear pretty right, as both Amsterdam and NY have DST in effect. If you try that with a zone that has no DST you'll be wrong by your DST offset, I think.

This seems to be correct also, so I think I can do this for any other city as well. Thanks very mucho
