Re: Time Signals

The pips rebroadcast are going to be inaccurate, but DAB spec includes a time sync signal that your receiver can use to synchronise its local clock to NAD accurate. If your receiver implements this properly then it wouldn't be too much of a stretch to generate local pips from the local clock.

Unfortunately some software clocks on some DAB receivers check the time sync every hour, and drift wildly over the interim. This is improving on later sets, interestingly cheapo unknown brand radios seem to get this right, syncing much more often.
