Cumulus Clock and PC Clock Different

Flosex · Post by **Flosex** » Thu 18 Sep 2014 7:56 am

I am located in West Sussex, UK and am running Cumulus on a Windows 8.1 computer with a Fine-Offset WH3080 weather station.

I have just had to change my weather computer running Cumulus to another computer that, because of other applications I run on it, has to have its clock set to GMT. After a few days, I have just realised that Cumulus is displaying GMT time (instead of my local time, which is UK BST time at the moment) and that my Cumulus records since changing computer are one hour out.

I assume I can edit those records in the dayfile.txt file to correct the time difference but, more importantly, how do I set up Cumulus to record and display data at my local time but with my computer clock set to GMT, please?

I have searched the Cumulus Help File, Google, etc, but cannot find this question having been raised before.

I have the same problem running Yawcam to display the webcam on my web-page, but have been able to overcome this to some extent by some appropriate wording of the text overlay, see <http://www.n4cj.com/yawcam.jpg> but if anyone knows how I can cure the problem properly with Yawcam, I would appreciate knowing, please?

Thanks for any help.

You can't; Cumulus gets the time from Windows, so whatever time Windows says it is, Cumulus uses that.

It's possible that at some future point I could add a facility to use a time offset from the system time, but it's a huge change which affects many places in Cumulus, so it's not something
I can do in the short term. It does seem to me, though, that it's the software that requires the system clock to be wrong that should be providing the facility...

Thanks Steve, I understand.

By the way, it is not the other software I run that requires the computer clock to be set to GMT, it is my choice, because the international environment in which I use it use GMT as the time day, regardless of where you are situated in the world. Of course, I only have the problem for six months of the year (end of March to the end of October) when we are on BST in the UK, the remainder of the year being on GMT.

Maybe you could run Cumulus in a virtual machine which always runs GMT?

Thanks Adrian but my wife says I have too many computers already!

Since making my last post i have found an option in the other software I use on the Cumulus computer that enables me to set the time to GMT for that program regardless of what time the computer clock is set.

Hi Chris,
I have the same problem as yours (a software for seismology uses GMT). What program did you find that setting the time?
Thanks.

Garoda.

Hello Garoda

The other software I was referring to is an amateur radio logging program. All radio amateurs throughout the world use GMT and fortunately I was able to find an option in the program for it to use GMT whereas my computer clock is set to UK time for Cumulus. If your seismology program doesn't have a similar option, then I don't know how you can get round it.

Good luck and regards
