Is that the exposure?
My understanding is that the match represents the moment that one of your prior contacts reported their positive test, rather than the exposure itself.
The only time I have been pinged during this pandemic was (probably) as a result of having a drive through McDonalds and the people in the car next to us (probably) testing positive a few days later.
I say probably, but on the day in question the only time we had been outside was for that cheeky Big Mac

I just got the ping about half an hour ago, looking at the settings on my phone, the timestamp is 13:14 (about 40 min ago), with 17686 keys, 1 match. Is that the exposure?
I think that is the time the database of infected phone ids was downloaded. Your phone then checks to see if it has seen any. The exposure you are getting a ping from was a few days ago as someone has to have a positive PCR and stick it in the app.
It could be a neighbour, bluetooth travels through walls.

How do the exposure notifications actually work? I just got the ping about half an hour ago, looking at the settings on my phone, the timestamp is 13:14 (about 40 min ago), with 17686 keys, 1 match. Is that the exposure? What time period is that from as I thought it was 15 minutes in close proximity to a positive case, and I've not spent 15 minutes with anyone but my wife or daughter in weeks. I've been to tesco, and driven my daughter to nursery. But even in Tesco, I would not have been close to the same person for more than a few seconds.
The timestamp was when I just happened to take my daughter out in the pushchair for a walk around the block to get her to sleep.
