Spectracom 1200 033 SECURESYNC MODULAR TIMING
Amazon's catalog no longer lists this product (checked 2026-11-02). The name comes from the link HN users posted.

Right. I'll download an open source database, then buy a commercial GPS clock and attach to it.

Only $12k for a Spectracom. Granted they are nice.
Well, I guess if it demonstrates anything is one fact -- if even Google needed GPS hardware to provide "latest" in a distributed system, then OP is right. Time in distributed systems is very hard.

Not sure if "simply" was mean sarcastic or not. If reliability and deletion of user's data is important, and it relies on getting NTP time, I would strongly advice not to use that distributed db system.
