[time-nuts] Re: Clock display on Linux systems?

[Anders Wallin]

We use this simple python script with RPi and a 7" RPi screen in many labs
just to have a simple clock display. AFAIK the timing and update rate is
good enough for human visual readout.
The RPis get time over NTP.

In this application RPis seem to last for many years - in others where we
use the SD-card (e.g. influxdb or similar) they seem to regularly fail in
1-2 years, requiring an reformat or new SD-card. An RPi or similar with a
more robust SSD/M2 drive would be good.
