I wonder if the blades also are in sync, either amongst themselves, or with GPS, or with the power grid frequency. /tvb

I'm using a python hack that shows both the T2 time string and the status page. When I set the date, the status page shows the new date. The T2 date doesn't change. When the GPS gets synced up, the T2 date and status page date both jump to goodness. -- These are my opinions. I hate spam.

That seems like an obvious hack, but it depends on the implementation details inside the FPGA. What's the granularity? How much does it change from chip to chip or over voltage and temperature? Has anybody published any data? ---------- Another possibility is to use trace delays on the PCB.

Microchip has some small modules from the division they got through the Symmetricom acquisition, but they are just small GPSDO, not network servers. https://www.microchip.com/en-us/products/clock-and-timing/components/gnss-gps-disciplined -- Chris Caudle
