I'm saying I doubt they will ever offer it precisely because it will conflict with their paid offerings. The fact that it takes its hardware is a great excuse to not give your customers the option.
I know GPS time sources have been available forever but a fault tolent database needs a backup. The US GPS is incredibly reliable but there have been multiple issues with both Glonass and Galilio.
It sounds like Google has an additional time source making this possible, probably a highly miniaturized atomic clock, possibly on a single chip. There's no way they're running on GPS alone
- detaro 10y agoYes, they clearly say that they use atomic clocks in addition, but that's commercially available as well. Atomic clock for frequency stability short- to mid-term, GPS to keep it synced to global time. E.g. in many cases, mobile-phone base stations contain just such a setup, and the data-center versions should fit in a few HE.

- detaro 10y agoA system build on top of it? Possibly, but thats the trade-off if you don't want to pay for/be lock-in to somebody else running it. For just the timing stuff: not really. Of course it adds complexity, but these things are established and should be quite stable.
