Time of rain logging Discrepancy by one hour early
Posted: Fri 06 Oct 2023 4:00 pm
I still run CU1 with a Davis Envoy and USB logger. This is at 10-minute interval logging and on a Windows 8 PC.
I also run CMX with a WiFi-logger and a WLL. These are at 5-minute interval logging and this on a Windows 10 pc.
As I was comparing the Cumulus 24 hour rainfall since 8:00 am yesterday to today 8:00 am for comparing to my daily CoCoRaHS submission I noticed the time for the rain in CU1 was logged one hour ahead of my CMX logging. Usually I just look at the Yesterday and Today rain on the CU1 console but this time I also looked at the CMX Today and noticed a difference:
All the other data items seemed to be about the same for each logged time (some minor differences due to 5-minute vs 10-minute logging), just the rain out by one hour. From my recollection around supper time yesterday, CMX is logged correctly, and that is also confirmed by my WU and PWS Weather uploads. I checked a previous time of some ongoing rain and that time CU1 and CMX logging was the same times. The PC date and time is the same on both PCs.
I will watch for it during the next rain...
Enjoy,
Paul
