The past few days I hadn't been paying attention so I missed that Midnite has joined the club. Her 12:12:13am (ET on the 21st, 09:12:13pm PT on the 20th) shows up as 05:12:13pm ET on the 20th - and her 12:26:26am (ET on the 21st, 09:26:26pm PT on the 20th) shows up as 05:26:26pm ET on the 20th.
Welcome aboard Flashed-back Time, Midnite!!
And I also noticed that yesterday I switched back and forth from normal time to flashed-back time and back to normal time in the same posting period. I went from 04:57:59pm ET to 10:19:45am ET to 05:22:33 ET while I was posting on the "Calendar Events / Announcements '19 I" board. It's the first time that's ever happened to me...
