Edit report at http://bugs.php.net/bug.php?id=49448&edit=1 ID: 49448 Updated by: derick@php.net Reported by: the_good_technician at yahoo dot com Summary: Sunset/Sunrise Zenith default values wrong -Status: Assigned +Status: Bogus Type: Bug Package: Date/time related Operating System: * PHP Version: 5.3.0 Assigned To: derick New Comment: Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php The algorithm code we use, clearly says: * altit = the altitude which the Sun should cross * Set to -35/60 degrees for rise/set, -6 degrees * for civil, -12 degrees for nautical and -18 * degrees for astronomical twilight. and -35/60 = −0.583333333.

I'm surprised nobody has reported it so far. The default configuration value for "date.sunrise_zenith" and "date.sunset_zenith" is "90.583333". But this value is incorrect! The correct value for a sunrise/sunset zenith angle is 90 + (50/60) WHICH EQUALS 90.83333333333 NOT 90.58333333333 Reproduce code: --------------- echo ini_get("date.sunrise_zenith") . "\n"; echo ini_get("date.sunset_zenith") . "\n"; Expected result: ---------------- 90.83333333333 90.83333333333 Actual result: -------------- 90.58333333333 90.58333333333 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=49448&edit=1
