I was recently troubleshooting a device that suddenly started cutting a minute or so off the start of some recordings.

There appears to be about a 2 minute time difference between the 2 Freeview transponders 12456 and 12483.

The time broadcast by 12483 seems to be more or less accurate, with the time broadcast by 12456 about 2 minutes slow.

Can anyone else confirm this behaviour?

Who controls the transponder time - Freeview, or the broadcaster?

Yes I discovered the same thing after missing the start of recordings.

The satellites are dumb pipes so it will be Freeview who collates the information (and programs) at the head end and sends to (I think) Kordia for uplink at Avalon in the Hutt Valley. The boxes at the headend will prob need adjusting.

Just want to confirm. You are talking about the DVB-S embedded time signal rather than programs appear to be off by 2 minutes?

You should use NTP as a time source as DVB based time signals are seldom accurate. For any recordings I always start 90 seconds or more early, and for most shows overrun by 5 minutes. If the show is something Live - eg X Factor NZ - the allow upto 30 minutes.

Correct - not talking about whether or not the broadcaster is sticking to the schedule, but that the embedded time is wrong.

If you flick between channels on different transponders, say TV2 & TV3, then the time changes by about 2 minutes as you move back and forth.

Well, for reasons not known to me, this appears to be resolved now, with the transponder embedded time being more or less the same across and transponders, and accurate.

Presumably someone changed the time somewhere, but we may never know!

Well, a similar problem seems to be back. Embedded time on 12483 seems accurate, with 12456 running about 2 minutes fast this time.
