    Time difference zip point naught 15 hours later between D4 on the PC and time on the mobile.

    Hm, that construction seems to work only on a flat earth that takes 12 hours for one rotation instead of 24.

    Or is there a hidden joke that I don't get?

    Well, you can’t use it at night.

    It works with software in your computer to change your clock. See:

    Maybe this could be done by the FT8 software itself. Today there were about 30 signals on 20m, most of them with less than 1s offset. I think you get a good time synchronization by calculating some mean value from the received offsets and adjust your time accordingly.

    My computer syncs to my cell phone using a WiFi connection.

    Seems that would be the easiest if you have a smart phone.

    There is also CHU - among WWV's and CHU's frequencies I usually find one I can copy well enough to get the time.
