How many time zones are there?

The question

Efficient

There are technically 38 different local time offsets used around the world.

While many people learn that there are 24 time zones—one for each hour of the day—this is a simplification. Because many countries choose to observe "half-hour" or "45-minute" offsets (such as India's UTC+5:30 or parts of Australia's UTC+9:30), the actual number of time offsets currently in use is 38.
