Computer clock advanced 1 hour

[PaulMy]

As part of my morning check I found that my sunrecorder chart was advanced 1 hour. Upon further checking found my computer clock the same. Checked my Cumulus data and there I could see that the log went from 2:50 am to 4:00 am so something made the change at 3:00 am. I don't have automatic Windows update set so will have to keep an eye to see if it happens again.

I changed the computer clock to the correct time, and copied the files from Cumulus' midnight backup to the current data folder, restarted Cumulus and all is well again including most data upload catch up. WU, CWOP, AWEKAS, WOW all seem to show correct data and graphs and the only thing I have seen is that my PWS data has a small drop in temperature from the correct 5.6C to -0.7C at the time I changed my computer clock and then back to the correct temp, and CWOP has no raw data for the missing hour. Well done Cumulus.
