PHP Bug Type: Date/time related
Bug description: date_sunrise and date_sunset don't handle GMT offset well.
Description:
------------
There seems to be a bug in date_sunrise and date_sunset when the GMT
offset is greater than the sunrise or sunset time.
For instance, if the date_sunset function returns '00:14' as the sunset
time in GMT, trying to use the GMT offset of -4 would result in '-3:-4'
being returned.
In sunfuncs.c there is a line:
ret = php_sunrise_sunset(N, latitude, longitude, zenith, calc_sunset) +
gmt_offset;
It seems that it should check if gmt_offset is greater than the returned
value from php_sunrise_sunset and if so, add 24 to the returned value
before the addition of gmt_offset.
Reproduce code:
---------------
<?php
echo date("D M d Y"). ', sunset time : ' .date_sunset(time(),
SUNFUNCS_RET_STRING, 40, -83, 90, -4);
?>
Expected result:
----------------
I would expect to see:
Sun Apr 24 2005, sunset time : 20:14
Actual result:
--------------
I actually see:
Sun Apr 24 2005, sunset time : -3:-4
