InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
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).
