Live TV like NHL games etc are all about 40-45 seconds behind as well as TV shows.... I watched new years count down and it was 1min and 20 seconds behind midnight.
4K channels always skip or freeze
Some live programming is delayed by the "broadcaster". In the US it's even mandated due to potential swearing, etc. I believe it's not quite as long as you mention though.
Have you tried looking at CP24? How does the time compare to actual time? I assume you're not doing "pause live TV" which will bring a delay of a few seconds into play as well.
There has been mention of 4K issues (see the TSN4K thread here, but it doesn't appear to affect everyone, so it may be signal related, or area specific, like the Ottawa head end.
Interesting, you say 6:15PM, however, the time-stamp on your post was 6:14. Are you sure you've got the "correct time" on the device you're comparing the box signals to? For example, I get the time on my Mac Mini automatically from the web and it agrees with CP24 on my 9865 PVR (within about 5 seconds with CP24 those 5 seconds behind due to digital box processing)
Do your programmes start recording "on time"? When you watch them back, do they start on the hour or half hour? Again, try CP24 or similar channel with time stamped information.
The time delay is not a concern for me, but here is my informal measurements compared to my Win 10 PC:
- Android phone is 2 seconds behind
- CP 24 is 27 second behind
- CNN is 35 seconds behind
I am in Markham.
