Server Version#:1.21.1.3830-6c22540d5 Windows 10 2004 Updated.
Player Version#:Samsung TV 2020 20_NIKEL_UHD_BASIC Plex Client 5.6.1
Samsung TV hard wired.
Live is SA Australia.
4 Oct 2020 - Daylight Saving Time Started
When local standard time was about to reach
Sunday, 4 October 2020, 2:00:00 am clocks were turned forward 1 hour to
Sunday, 4 October 2020, 3:00:00 am local daylight time instead.
Problem is that the Plex time is 30 minutes ahead of the TV time so when the TV time is 12:00pm the Plex time is 12:30pm.
I did report this problem back in Feb 2020 but of cause in April 2020 DLS Finished and the problem went away, but this time the time is not 1 hour behind like it should be so either you have tried to fix the problem and failed or something else is a going on.
