Arguments
lng
The longitude in degrees (east of Greenwich) of the place for
which the local sidereal time is desired, scalar. Greenwich
mean sidereal time (GMST) can be found by setting lng = 0.
tz
The time zone of the site in hours, positive East of the Greenwich
meridian (ahead of GMT). Use this parameter to easily account
for Daylight Savings time (e.g. -4=EDT, -5 = EST/CDT).
This scalar parameter is not needed (and ignored) if Julian date is
supplied. Note that the sign of TZ was changed in July 2008
to match the standard definition.
tme
If more than three parameters are specified, then this is
the time of day of the specified date in decimal hours. If
exactly three parameters are specified, then this is the
Julian date of time in question, scalar or vector
day
The day of the month (1-31),integer scalar or vector
mon
The month, in numerical format (1-12), integer scalar or vector
year
The 4 digit year (e.g. 2008), integer scalar or vector
