your system clock should really always be UTC, as a global, universal even, standard. Software level "overlays" of this should then personalise it at the last minute to make it locally suitable to you.
Whilst it can be said to be 8am in London / UTC and it's what... 3pm or something in Japan it's still "NOW!" everywhere, and ultimately a timezone and HH:MM:SS notations are just prettying up conventions, your system clock should still be keeping track of the time in the whole universe. (well, save for singularities and that freaky stuff)
