Almost ten years ago I recycled/converted Topfield to show time with an arduino-like board and a network adapter. Basically, it listens to NTP broadcast messages and "keeps" time in between. Its timekeeping will suck though if it won't receive the messages periodically, but in practice it's quite fine. Except once when the ethernet board somehow broke down; fixed it by replacing it. Here's a short writeup I did for hackaday: https://www.modeemi.fi/~flux/projects/TopfieldClock/ https://www.modeemi.fi/~flux/projects/TopfieldClock/
