 -days 60

This option specifies the number of days to cover.

The default is -days 30.


 -format %Y-%m-%dT%H:%M:%S

This option specifies the strftime (3) format used to display the time.

The default is -format '%d-%b-%Y %H:%M:%S %Z'.


If asserted, this Boolean option attempts to display the time in GMT. All that it really does is

 local $ENV{TZ} = 'GMT';

which may or may not have the desired effect.

The default is -nogmt.


This option displays the documentation for this script. The script then exits.


 -start tomorrow

This option specifies when the computation starts, as a date and time understood by Date::Manip.

The default is the current date and time.


This option displays the version of this script. The script then exits.


This Perl script calculates the quarters for the bodies specified on the command line, or for all bodies if none are specified. The command line is not case-sensitive, but must specify bodies supported by Astro::Coord::ECI::VSOP87D.

The times displayed are local unless -gmt is asserted.
