The signal is only used (as far as I am aware, a few Time Nuts apart) for
controlling domestic electricity time switches for people on the
"Economy-7" tariff, which gives them cheaper electricity overnight for
storage heaters for seven hours.  As such, I suspect even a fraction of a
second is overkill.
