What's the time and date in Alice Springs

Question

very complicated .... 

 If the time in Alice Springs Australia is nine hours and 30 minutes ahead of the time in London and the time in San Francisco USA is eight hours behind the time in London and it is 9:23 AM and 30 September in San Francisco what is the time and date in Alice Springs 

Answer 1

If it is 9:23 a.m. in S.F. and S.F. is 8 hours behind London, then what time is it London?

 

It is 5:23 p.m. in London, and it is still Sept. 30.

 

Now, Alice Springs is 9 hours ahead of London. Another way of thinking of this is London is 9 hours behind Alice Springs.

 

That means it is 2:23 a.m. and Oct. 1 in Alice Springs.
