PHP Bug Type: Date/time related
Bug description: date_sunrise() date_sunset() handle main zone offset but not
count summer time
Description:
------------
In php_date.c I see some (unsuccessful) effort to calculate proper offset,
I mean line
gmt_offset = timelib_get_current_offset(t) / 3600;
but it gets only _main_ zone offset, without current summer time added.
I.e. for Europe/Moscow it _always_ gets 3, but in the summer it must be
4.
This code can't work in any case, because it consider 'time' argument only
few lines later:
timelib_unixtime2local(t, time);
but at the moment timelib_get_current_offset(t) called, 'time' arg simple
unused, so you can't get summer offset this way, only main one.
Please fix the code to count summer time too,
Reproduce code:
---------------
I have following lines in my php.ini:
date.default_latitude=55.75
date.default_longitude=37.61
date.timezone=Europe/Moscow
and call this test script when summer time (+0400) is active:
<?php
echo date("r").', '.date_sunrise(time()).', '.date_sunset(time());
echo date("r").',
'.date_sunrise(time(),SUNFUNCS_RET_STRING,55.75,37.61,90.583333,4).',
'.date_sunset(time(),SUNFUNCS_RET_STRING,55.75,37.61,90.583333,4);
?>
Expected result:
----------------
Two echo calls must produce the same sunrise/sunset results when summer
Moscow time (GMT+4, specified directly in the second echo call) is active.
Actual result:
--------------
Sunset/sunrise time of the first echo is one hour behind (GMT+3), when
script called with summer time active.
date() call itself reports +0400 properly.
Moreover, I consult astronomical tables, first sunrise/sunset is
definitely one hour behind.
