Essentially the Malcolm Hulke version of The Happiness Patrol. ( )

Steve Lyons' work is always interesting, and Time Works is no exception: the Eighth Doctor and friends end up in a society obsessed with timekeeping, enforced by mysterious clockwork robots (a foreshadowing of The Girl in the Fireplace, unintentionally no doubt). The story combines the standard overthrow of alien oppressors (though not the king, this time) with some plot-convenient timeslips, so is not particularly special, but the dialogue is cracking, the world-building unusually convincing, and the cast, especially McGann, on top form.
