What time does the Nexus 4 release in the Google Play Store? - UK

Yes, I realise it's quite a sad question, but I would like to know. I don't want to go to bed before midnight on the 12th and wake up on the 13th to find that it's out of stock.

The reason I assumed that it wasn't midnight was because that would mean that the US would get the phone a few hours later, and I wouldn't have expected that to happen with almost any international product, especially when Google are American in the first place.
