Time-Appliance-Project reviews and mentions
- Time Card Mini Adds Pi, GPS, and OXCO to Your PC
-
Meta's Reality Labs lost $3.99 billion last year, bringing its total losses since 2020 to $30 billion
Even just specific projects under that have been impactful. For example the open time server project.
- What’s the most granular magnitude of time (Picosecond, Femtosecond, etc.) that a CPU can return when it’s queried for system time?

New atomic clock loses only one second every 300B years
Facebooks Time Card is a good starting point if you want to start looking into how higher end timing devices are built: https://github.com/opencomputeproject/Time-Appliance-Project...
Afaik its not currently available for purchase, so it is more of a diy route. If you want a standalone unit, it probably wouldn't be too big of hassle to ducktape that Time Card to e.g. Raspberry Pi CM4 or similar module with pcie and drive a display (or whatev) that way. Or that FPGA on the Time Card probably has enough spare capacity to do it directly too, for a simplified architecture (and maybe better hard realtime control).

Time Card
Time Card is an open-source solution for PTP-enabled networks that provides the accurate time via GNSS—with a high stability (and holdover) oscillator such as an atomic clock as a backup in the event of GNSS failure. zeroibis recommends it for those who "need to go the full self-hosted NTP route."

Facebook open-sourcing a more precise time server
Really nice of them to release this. However, unless I'm missing something, the HDL for the FPGA on the Time Card is not part of the release. It looks like it uses a proprietary IP core from NetTimeLogic
https://github.com/opencomputeproject/Time-Appliance-Project...
They do include FPGA bit streams, but it's disingenuous to claim a fully open source release.
