date_sunset
Description
mixed date_sunset (int timestamp [, int format [, float latitude [, float longitude [, float zenith [, float gmt_offset]]]]])date_sunset() returns the sunset time for a given day (specified as a timestamp) and location. The latitude, longitude and zenith parameters default to the date.default_latitude, date.default_longitude and date.sunset_zenith configuration options, respectively.
The latitude defaults to North. So, if you want to specify a South value, you must pass a negative value. The same note applies to longitude, which defaults to East.
The gmt_offset parameter is specified in hours.
