Just to make things more complicated, civil time in the UK is GMT (approximately UT1) and *not* UTC. So clocks should never have 23:59:60. De jure yes, but it is de facto UTC. GMT hasn't been maintained for decades and almost all the UK government-sponsored time signals provide UTC without DUT1.
MSF provides DUT1. -- Clive D.W. Feather | If you lie to the compiler, Email: clive@davros.org | it will get its revenge. Web: http://www.davros.org | - Henry Spencer Mobile: +44 7973 377646
