TCL tv 7121x, Roku os 12.5.5.4174
Home Screen shows correct time. Bringing up antenna tv guide shows time, and guide, about 19 minutes ahead. Example, Home Screen shows 7:43 pm edt, guide shows 8:02 pm. (And doesn’t show what is on at the current correct time). I’ve tried restart, which sometimes corrects it, but only for a few moments, I’ve tried unplugging— same result.
