One of -l or -r must be specified.

T: Universal Time (otherwise current local time) (hhmmss)
d: current date (otherwise current local date) (yyyymmdd)
g: longitude (decimal)
t: latitude (decimal)
p: planet name (only first one or two characters are used)
ENVIRONMENT
planet looks for the following special environment vari-
ables:
LATI - latitude to use (decimal degrees)
LONG - longitude to use (decimal degrees)
ELEV - elevation to use (meters above sea level)
as well as the standard time variable TZ (PST8PDT for the
