You don't say if the clock is analogue or digital, I had an analogue clock with the same problem and all it turned
out to be is that the big hand had somehow got lose on its spindle, I simply removed the front glass cover,
manually turned the big hand to the correct position and replaced the glass... Simples..

Most radio clocks work in much the same way as a standard quartz clock – the only difference being that they respond to a synchronisation signal (normally once a day), and adjust accordingly.
People incorrectly believe that these clocks are very accurate, but in reality you would achieve the same result, resetting a quartz clock once a day manually, to a time signal broadcast on your radio.
Tell your friend to move the clock to a location where it will receive a stronger signal e.g near a window. Otherwise to buy a standard quartz clock, these days most have an accuracy of better than 5 seconds a month – if your friend needs to know the time more accurately than that, they are very sad.

Even bidding on ebay at the last minute (second), does not require a particularly accurate clock.
I regularly bid within the last 5 seconds (using my 30 pence alarm clock for time indication), which does not give enough time for some one to manually enter a higher bid.
To make things easier for last minute bidders on ebay, items now show a count down to their auction end by the second. Anyone with a time-piece having a second hand has the power to make a last second bid – no need for atomic clocks to achieve that.
