I figured out a workaround to this bug.
you have to add -1 day to subtract one day from sunrise and sunset
times.
if ($offset >= 12 && strcmp(date_default_timezone_get(),
"Pacific/Tarawa") != 0) {
echo "+12 GMT workaround done<br>";
$sunrise = strtotime('-1 day', $sunrise);
$sunset = strtotime('-1 day', $sunset);
$csunrise = strtotime('-1 day', $csunrise);
$csunset = strtotime('-1 day', $csunset);
$nsunrise = strtotime('-1 day', $nsunrise);
$nsunset = strtotime('-1 day', $nsunset);
$asunrise = strtotime('-1 day', $asunrise);
$asunset = strtotime('-1 day', $asunset);
}
I need to test on time zones that are -12 in offsets
might have to do +1 day on that offset.

Description:
------------
when you try to get sunrise and sunset times from the area that have GMT
+12 or over. the sunrise and sunset times will be listed for next day.
The sunrise and sunset times should be listed for today.

the source code is at http://weatherpixel.com/bug.php?src=show
one of the examples that the Fiji Island times would only show for
tomorrow and
my script would show it as night as always.

Here is my configure line for linux:
./configure --enable-sockets --enable-calendar --with-curl=/usr/lib/
--with-gd --with-jpeg-dir=/usr/local/lib --with-png-dir=/usr/local/lib
--with-ttf --enable-gd-native-ttf --with-gettext
--with-freetype-dir=/usr/local/lib --without-sqlite --without-pdo-sqlite
--with-apxs2=/usr/local/apache2/bin/apxs
Test script:
---------------
here is php script that reproduce the date_sunrise
http://weatherpixel.com/bug.php?src=show
Expected result:
----------------
the times for +12 GMT and more than +12 GMT will always show tomorrow's
sunrise and sunset times.
