CSPICE_TYEAR returns the double precision value of the number
of seconds in a tropical year: 31556926.
For important details concerning this module's function, please refer to
the CSPICE routine tyear_c.
No input required.
sec_tyear = cspice_tyear()
A double precision scalar, the number of seconds per tropical
year. This value is taken from the 1992 Explanatory Supplement
to the Astronomical Almanac.
Any numerical results shown for this example may differ between
platforms as the results depend on the SPICE kernels used as input
and the machine specific arithmetic implementation.
IDL outputs: 31556926.
