Top of the head idea:

- get a cheap "Atomic Time" clock with the display format you want.

- GPS receiver with Raspberry Pi/Pico/Arduino or similar to get the time and
GPS offset (use GPSD?).

- extract the GPS time offset to create the time /you/ want.

- code a simple emulation of WWVB/MSF/DCF-77 or whatever and make the Pi
generate a simple 60 kHz signal with the right modulation and feed it to (near)
the cheap "Atomic Time" clock.

RPi TX software can make the RPi into a transmitter:
