If I understand your issue, your time is showing 1 hour off of what it’s supposed to be. If that’s correct, look at the time zone your system is set to and if your locale observes daylight savings time; both of these adjust the time by an hour.
That being said, my system time is an hour off when using the date command via console, but shows correctly on the phones & in the GUI. No idea why… it’s the only linux system I have (out of over a dozen) to do this. Only thing it really impacts is the timestamp in the log files, so I decided to ignore it after failing to diagnose it on here.
Best of luck to you; if you figure it out, please report back what caused it.
