Ok, so here we go... ready.....
HongKong '3' users were text from '3' to say that the update will occur at 1am their time, that figured against UK time is 6pm (as stated earlier) also tallies up with California time stated too.
Workers from o2 have received an email from Apple (or whoever) to say that the update will be ready at 6pm today....
... check the o2 site out:

Clearly states "Available this evening"
I think the puzzle is coming together - slowly!
