    Following on the posting from Cees Bassa on timing problems, and
    the posting from Tom Troszak on the US phone number:
    the phone number may may accessible from Europe, but a call may go via
    a satellite, which would mean a few tenths of a second delay.
    Safer to either use a more local phone number (I suspect the UK speaking
     clock is not accessible outside UK), or radio.
    Near the UK the BBC long wave 198 Kcs gives a time signal at most hours,
    and the BBC World service gives time signal at most hours on short wave
    to all the world, and medium wave in selected places: details from
    Also on short wave at 10Mcs there are pips each second (with a long pip
    on the minute) from 10 to 20 minutes past each hour & from 40 to 50
    minutes: this I think comes from Moscow. There may still be similar
    signals on 5 & 20Mcs, I have not tried recently.
    Other shortwave frequencies worth a try are:
           2.5 3.330  7.335 14.670  15.0 MHz.
    There may be medium wave time signals near you, try listening after dark
    on the hour.
    There is also an ultra-long wave signal from Germany, I cant find its
    frequency right now, perhaps 16Kcs or 40Kcs.
