Bug description: sun_rise and sun_set don't return a GMT timestamp if one passes an offset

Description:
------------
With my current version of PHP5 (5.0.4-0.6.sarge.1 (Debian GNU/Linux) I
run into an error if I use date_sunrise and date_sunset. This happens when
I pass an GMT offset and results in a timestamp that has an offset of +1
hour to the actual sun set/rise on that date. Since timestamps are GMT/UTC
and not bound to an timezone other that GMT/UTC this is wrong. I say this
since I believe the GMT offset one can pass to the before mentioned
functions is used in the calculation and the functions should return a
timestamp like any other so it can be used by date and gmdate as those
functions require a GMT/UTC timestamp...

B.t.w. I use the max difference for some further calculations in my
script, so there for the lage difference between astro and official
sunset's/rises...

Reproduce code:
---------------
$latitude = 28 + (1/60*17) + (1/60/60*54);
$longitude = (-(16 + (1/60*30) + (1/60/60*34)));
$astro = 108;
$official = (90 + (1/60*50));

echo "Local Tenerife time<br>\n";
echo "sunriseAstro = " . gmdate("M d Y H:i:s", date_sunrise(1121208238,
SUNFUNCS_RET_TIMESTAMP, $long, $lat, $astro, 1) + 60*60) . "<br>\n";
echo "sunriseOffical = " . gmdate("M d Y H:i:s", date_sunrise(1121208238,
SUNFUNCS_RET_TIMESTAMP, $long, $lat, $official , 1) + 60*60) . "<br>\n";
echo "sunsetOffical = " . gmdate("M d Y H:i:s", date_sunset(1121208238,
SUNFUNCS_RET_TIMESTAMP, $long, $lat, $official, 1) + 60*60) . "<br>\n";
echo "sunsetAstro = " . gmdate("M d Y H:i:s", date_sunset(1121208238,
SUNFUNCS_RET_TIMESTAMP, $long, $lat, $astro, 1) + 60*60) . "<p>\n";


Expected result:
----------------
Local Tenerife time
sunriseAstro = Jul 12 2005 05:47:50
sunriseOffical = Jul 12 2005 07:02:02
sunsetOffical = Jul 12 2005 19:09:17
sunsetAstro = Jul 12 2005 20:23:27

Actual result:
--------------
Local Tenerife time
sunriseAstro = Jul 12 2005 06:47:50
sunriseOffical = Jul 12 2005 08:02:02
sunsetOffical = Jul 12 2005 20:09:17
sunsetAstro = Jul 12 2005 21:23:27
