date_sunrise --  Returns time of sunrise for a given day and location

Описание

mixed date_sunrise ( int timestamp [, int format [, float latitude [, float longitude [, float zenith [, float gmt_offset]]]]] )

date_sunrise() returns the sunrise 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.sunrise_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.
