It's generally useful to know that there's been a main cut as we used to get one or two a week some time ago. CH timers, video recorders etc. may be put wrong. Plus, WWII-period bakelite mains clocks are getting quite valuable as collector's items so they're a good investment.

Radio 4 LW is still transmitted from Rugby, so the situation is more complex than the URL shows.
The Rugby Radio Station is a large site which originally had many transmitters from the 16kHz "GBR" station used to talk to the colonies to multiple shortwave analogue radio telephone. It is the 60kHz MSF VLF transmitter that is currently shutting down. The 16kHz VLF has already gone. I don't know what is left, if anything.
However, it does not include the Radio 4 LW service. The nearest transmitter for that is at Droitwich, SW of Birmingham.
Domestic clocks are also for those of us that don't wear watches.
As far as the original question is concerned I'd simply ignore the socket (perhaps putting a plug in it to neaten it up a bit), or hang a clock in front of it. It might be possible to power the clock from the socket but I wouldn't bother, I'd use a battery-powered radio-controlled clock.
Incidentally does anyone know where to get a battery-powered radio- controlled wall clock featuring a proper mechanical display with hands and the *date*? And for bonus points, the day of the week?

Different thing. There is a signal sent specifically to switch over Economy 7 (world's greatest sarcasm) meters. It isn't a synchronising or timing application.
Not battery-powered (and certainly not cheap) but Wharton master clocks have mechanical and LED displays.
You *might* be very lucky and get from ebay an impulse-driven slave clock for offices which had a day indicator, and would then have to built an impulse generator. Battery or mains-powered clocks with flapperboard indicators for day/date were quite common in banks, as apart from telling customers what date to put on cheques etc, they were a convenient way of time-stamping security camera film (early security cameras used film and were triggered by under-counter bandit alarms).
It is, however, a frequency standard, in that the carrier wave is very precisely 198kHz, not 198.00001 kHz. You could certainly use it to regulate a clock, although it won't tell you the actual time.
