Here's a short explanation of the configuration directives.
date.default_latitude
float
The default latitude.
date.default_longitude
float
The default longitude.
date.sunrise_zenith
float
The default sunrise zenith.
date.sunset_zenith
float
The default sunset zenith.
date.timezone
string
The default timezone used by all date/time functions. Prior to PHP 5.4.0, this would only work if the TZ environment variable was not set. The precedence order for which timezone is used if none is explicitly mentioned is described in the date_default_timezone_get() page. See List of Supported Timezones for a list of supported timezones.
Note: The first four configuration options are currently only used by date_sunrise() and date_sunset().
