That is what the parameters are actually called in the source, so I'll punt this back to the
ext/date bug queue rather than documentation for now.

Description:
------------
See the documentation at http://us2.php.net/function.date-sunrise and at
http://us2.php.net/manual/en/function.date-sunset.php
zenith:-
This is the point on the celestial sphere directly above the observer's head and
will have no bearing on the calculation whatsoever. 'zenith = 90' makes no sense
at all.
The term you are looking for is 'azimuth', which is used in sunrise, sunset
calculations to tell if the bearing of the sun from the observer is East or West
of North.
Hence, the 3rd parameter in these functions should be 'azimuth' and not
'zenith'.
