Bug #46670 [Com]: date_sunrise (date_sunset) works incorrectly with gmtoffset parameter

Edit report at https://bugs.php.net/bug.php?id=46670&edit=1 ID: 46670 Comment by: mattleff at gmail dot com Reported by: andrewboltachev at gmail dot com Summary: date_sunrise (date_sunset) works incorrectly with gmtoffset parameter Status: Open Type: Bug Package: Date/time related Operating System: UNIX PHP Version: 5.2.6 Block user comment: N Private report: N New Comment: I am wondering if this is a documentation change, since the code appears to intentionally ignore the offset for SUNFUNCS_RET_TIMESTAMP: https://github.com/php/php-src/blob/master/ext/date/php_date.c#L4916-L4919 Otherwise this would be a trivial fix. Previous Comments: ------------------------------------------------------------------------ [2008-11-25 20:13:13] andrewboltachev at gmail dot com Description: ------------ date_sunrise (date_sunset) incorrectly works with gmtoffset parameter. When i use SUNFUNCS_RET_TIMESTAMP, it ignores it and calculates date by adding UTC sunrise date and my location offset. When use SUNFUNCS_RET_STRING, all is ok. I don't checked SUNFUNCS_RET_DOUBLE. Reproduce code: --------------- <?php $lat = 43.1167; $lng = 131.9; //Vladivostok, Russia, UTC+10 date_default_timezone_set('Europe/Moscow'); //My location timezone, UTC+3 $zenith = 90+50/60; $offset = 10; //Vladivostok $sunrise_str = date_sunrise(time(),SUNFUNCS_RET_STRING,$lat,$lng,$zenith,$offset); $sunrise_time = date_sunrise (time(),SUNFUNCS_RET_TIMESTAMP,$lat,$lng,$zenith,$offset); echo "By string : $sunrise_str, by timestamp: ".date("Y-m-d H:i:s",$sunrise_time)."<br/>\n"; $offset = 0; //UTC $sunrise_str = date_sunrise(time(),SUNFUNCS_RET_STRING,$lat,$lng,$zenith,$offset); $sunrise_time = date_sunrise (time(),SUNFUNCS_RET_TIMESTAMP,$lat,$lng,$zenith,$offset); echo "By string : $sunrise_str, by timestamp: ".date("Y-m-d H:i:s",$sunrise_time)."<br/>\n"; $offset = 3; //UTC plus my timezone offset $sunrise_str = date_sunrise(time(),SUNFUNCS_RET_STRING,$lat,$lng,$zenith,$offset); $sunrise_time = date_sunrise (time(),SUNFUNCS_RET_TIMESTAMP,$lat,$lng,$zenith,$offset); echo "By string : $sunrise_str, by timestamp: ".date("Y-m-d H:i:s",$sunrise_time)."<br/>\n"; ?> Expected result: ---------------- By string : 08:16, by timestamp: 2008-11-25 08:16:18 By string : 22:16, by timestamp: 2008-11-24 22:16:18 By string : 01:16, by timestamp: 2008-11-25 01:16:18 Actual result: -------------- By string : 08:16, by timestamp: 2008-11-25 01:16:18 By string : 22:16, by timestamp: 2008-11-25 01:16:18 By string : 01:16, by timestamp: 2008-11-25 01:16:18 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=46670&edit=1
