I noticed that my imaged server is also on UTC after my Raspian-based server, which is on EDT, failed to record two 6PM Newscasts. I had taken it down briefly to copy one of its backups and later found it "idle" and those jobs "pending" while it should have been recording them. I had no problem sampling one of them live with the web client other than the usual transcoding stutter. The log contained no entries for those jobs, but it contained some timestamped entries for a clock time that hadn't happened yet. Refreshing the guide seemed to correct the log and it recorded SNL perfectly several hours later. I may have booted it a minute before I remembered to reconnect it to my network, but otherwise I have no explanation for why it acted up. I was careful not to write to its drive while it was down for copying.
The imaged server with its passes restored from the copy recorded both newscasts and SNL flawlessly despite being on UTC.
