How Time Zones Work
Earth is divided into 24 standard time zones, each ~15° of longitude. But political boundaries create 40+ variations. Key facts:
- UTC is the reference (0 offset)
- DST shifts clocks forward 1 hour in summer
- Some regions (Arizona, Hawaii) don’t observe DST
- China uses one time zone despite spanning 5 geographically
