UTC Trend offset

Post by orfeo » Mon 16 Jul 2018 7:48 pm

Hi,

I've setup CumulusMX and my trends page, http://www.atmosp.physics.utoronto.ca/wstat/trends.htm, has a offset. The computer/station that logs the data is set to UTC time but the location of the station is Toronto. The theoretical solar value shows a 12hr offset from our solar rad data, Is this related to our UTC time setting? It doesn' seem to make sense as we are only UTC -4 at the moment but i am a litter uncertain why the theoretical is so far off.

cheers

Have you set your co-ordinates correctly? Are you really East of the meridian?
