Plex for Mac 1.45.0.3013 & 1.46.1.3056 Live TV & DVR EPG Display Skewed ~24 from "Now"

It appears that this bug is the same as reported 3 months ago by RobertB345 in the topic:

RobertB345 indicates his PMS server is using ET, so it seems to be demonstrating the same 00:00 UTC Live TV > Guide display bug. Other posters in RobertB345’s topic that have listed time specific details seem to correlate (eg, UK user with 12:30am – 1:00am issues, presumably BST [UTC +100])
