Question

HOW DO WE USE TIMEZONES ?

Answer 1

I live in the Central Time Zone in the US. My mother and brother live in the Pacific Time Zone. I always have to remember not to call them before about 10 am (my time)! And they need to remember not to phone me after 8 pm (their time).

Answer 2

We use time zones to standardize the local time with others in the world. If we didn't have time zones, it would be getting light at 7 a.m. one place and getting light at 7 p.m. somewhere else.
