Cumulus Support

In the Cumulus station configuration I have the setting for logs to roll over at 9.00 a.m. On the website it says the Meteorlogical day is 10 -10 a.m. It appears, as the minimum for today so far is at 10.00am not 9.00 am, that it is working to the latter?

British Summer Time. If you use 0900 as per Met Office standards, it changes to 1000 in the summer.

I thought it might be something like that but I hadn't realised the Met Office stuck to GMT. I think I might revert to midnight to midnight then today's mimimum will make more sense to most people.
Thanks, Dave

I've been thinking of switching to midnight myself. It probably does make more sense to most people viewing the data.

It's funny that you've brought this up now, I had just been thinking of dropping support for 0900 in Cumulus 2. It makes the programming so much more complicated. I was going to run a poll to see how many people use 0900. I know Paul does, but he's a proper official weatherman.

New Zealand is officially 9-9 Met Day most of use here use it to remain in line with the figures published by our Met Service

9 to 9 is a good option to have.

Outside the UK, when you use 9-9, do you switch to 10-10 during daylight saving time, as in the UK (so effectively using the same 'real' time all year round).

Cumulus assumes that you do.

I believe we do, but am in touch with the local Officios to find out for certain.

Thankfully don't have to worry about Daylight Saving Time. What a waste of time is DST!

So really there should be an option to include/exclude DST.

I agree with you completely.

Do you mean you don't have DST where you are, or your weather observation times don't change with DST?

We don't play DST here either. The entire State of Arizona stays MST (Mountain Standard Time or -7 GMT) with the exception of the Apache Nation which is in the upper corner of the state.

There is a special TZ designation for Arizona because of that US/Arizona

We don't have DST at all.

Never really thought about how DST affects historical weather data as I have never had to worry about it? All my stations are set to completely ignore anything to do with DST.

Probably best to ignore DST for weather data recording (that's effectively what the UK met office do).

Anyone who is running Cumulus and has their computer and weather station set to do DST changes (I do this myself, I shouldn't really) will find they get an hour's worth of duplicate-timed data next Sunday (or whenever).

Should have been logged in UTC
