Newbie question here - I’ve just set up HA on my Ubuntu server and got to work adding components but the first thing I notice is that every status panel from the dashboard gives me a date error regarding the start date being after the end date:
Invalid data at row #1: start(Thu Oct 27 2016 16:00:00 GMT+0100 (BST)) > end(Thu Oct 27 2016 15:14:48 GMT+0100 (BST)).
I have a timezone configured in the configuration.yaml and I also tried a restart removing the database.
I had a similar error message recently when we switched to daylight savings time. The errors were gone after 24 hours, so I was suspecting some code issue making a false assumption on available historical data.
Would be interesting to see if your problem is intermittent, too.
My error was caused by the system clock not having synced correctly with the NTP server - after I corrected this in the system config the problem went away. Perhaps your issue was similarly corrected by a forced re-sync of system time, depending on your config of course. Even if the system clock is wrong, however, I wouldn’t have expected this issue - it indicates to me that the start and end dates for the graph queries are being calculated from two different time sources.
