Clock issues with an Alecto WS-5000
Posted: Wed 12 Feb 2014 7:30 pm
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!
