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.
