stime - print current time information to standard out



  stime UKIRT

  stime -epoch 837459706 JCMT

  stime -h


This program prints current local time, UTC, Julian date, modified Julian date, current equinox and year day to standard output. Additionally, local sidereal time for the specified telescope is also displayed.


The optional argument can be used to specify the details for a particular telescope. This affects the local sidereal time calculation. The default is for the LST of Mauna Kea to be listed (specifically the James Clerk Maxwell Telescope). The sidereal time does not reflect the longitude of the computer used to run the command.

The format of this string is identical to that required by slaObs routine in the Astro::SLA package.


The following command line options are supported:


Override the time for which the LST will be calculated. By default will use the current time/date. This epoch should be supplied in seconds in the Unix epoch (essentially the argument to the perl localtime/gmtime functions).


Simple help message.
