Question

A cricket match begins at 10.30 am on January 10 in New Zealand (time zone of $+12$). What is the time in Greenwich when it is shown live on TV there?

Answer 1

The time at which a cricket match begins at New Zealand = 10.30 a.m. on January 10

Time difference between Greenwich and New Zealand = 12 hours

So, the time at which the same match will be aired at Greenwich = 10.30 a.m. - 12 hours = 10.30 p.m. on January 9.
