Clock issues with an Alecto WS-5000

Hi, I'm busy with my weather station for my backyard observatory http://sterrenwachtmyrtha.waarnemen.com/index.htm. A
After playing around with it for a few weeks I noticed a few strange things (note that I'm sitting in time zone GMT+1)

- The WS-5000 has a built-in DCF-77 clock. That reads only the correct time when I set the time offset setting in the EasyWeatherPlus 1.0 software from Alecto to 0 (which is strange, because I'm in time zone GMT+1.....
- When I set this time offset to 1, then the clock on the display of my weather statoins reads 1 hour too eary, so this time is just automatically added to the measured time from the DCF-77 clock: that means I should set this offset setting to 0.

Since I'm an amateur astronomer I'm very interested in the rising/setting time of the moon and sun. For some kind of reason these times (which are calculated by Cumulus, as far as I know) are always 1 hour too high, both for the Sun/moon rise and setting times.......

I use on the server that runs Cumulus 1.9.4 WinXP SP3 with correct time zone adjustment (GMT+1) and automatic daylight saving changes.
In cumulus I set the latitude correctly to my location 51.38.39 North and the longitude also correctly, which is 5.13.41E...

Can you experienced guys shine a light on this problem? Thanks!

On your web site, the sunrise and sunset times that Cumulus has calculated are 07:59 and 17:48.

I believe you are not far from Eindhoven? This web page gives the sunrise and sunset times for there as 07:58 and 17:48 - http://www.timeanddate.com/worldclock/a ... tml?n=1300

The moon times are also within a couple of minutes.

Thanks for checking. I was a bit confused because the website of a fellow astronomer had a mistake in it that sent me off the right track....
