SYSTIME() was upgraded in V5.4 so that systime(1) is supposed to return GMT
on all systems. (I believe that it used to return GMT on Windows and Unix,
but local time on VMS and MacOS.)
SYSTIME(0) always returns local time (as in earlier IDL versions), but now
one can also return GMT using the new /UTC keyword. Also, note that one
can now directly return the Julian date with the /Julian keyword.

(Universal Coordinated Time (UTC) was formerly known as Greenwich Mean Time
(GMT). )
