Recent OTA recordings have been starting a few minutes early and ending a few minutes late.
I compared the same programming with that on my older Tablo Four and time sync was OK.
There should be a way to see the Tablo device time to verify it is correct or at least very close.
Question: do the Tablo devices sync with an NTP server and if so how often? Multiple times or only after a restart, perhaps?
Correction: I should have said ending early rather than late. Mea culpa.
I’ll try a power-cycle on the device to see if that helps. It may have gotten confused stitching together the 10-second thumbnails in the series. (BULL).
Would it make sense that if there was a system clock time error, a recording would both start 2 minutes early and end 2 minutes late. If it was a clock error wouldn’t the recording start 2 minutes early and also end 2 minutes early.
I just noticed the recording of the series BULL SOMETIMES defaults to the streaming FAST channel ION rather than the OTA channel ION 54.1. Perhaps that might explain the timing error.
Question: any way to force recordings only on OTA rather than FAST or vice-versa? I can tell the broadcast channel resolution for OTA signals, but how can I tell the channel resolution of a FAST broadcast which may be lower resolution than OTA?
Also, many ISP have streaming limits, which would be another reason to prefer an OTA broadcast over a FAST broadcast for the same movie.
Each time your Tablo OTA DVR turns on, it will check for something called the Network Time Protocol (NTP) which tells the system what year, date and time it is in your location. Your home router will pass this info on from your ISP, which identifies your location based on your IP address.
Without the correct time, your Tablo will either think it’s been put into a time warp back to 1970, or if it gets the right date but the wrong time, schedule recordings or show a live TV grid for the incorrect time slot.
TV-connected Tablo DVRs do fetch time from NTP upon setup and check on it regularly to keep the time accurate, but also have an internal clock as backup.
