UTC (Coordinated Universal Time) is the global time standard. All time zones are expressed as offsets from UTC — for example, New York is UTC−5 in winter (EST) and UTC−4 in summer (EDT) due to Daylight Saving Time.

Daylight Saving Time (DST) shifts clocks forward 1 hour in spring and back in autumn in most of North America and Europe. Not all countries observe DST — China, Japan, India, and most of Africa do not.

Half-hour and 45-minute offsets: Some time zones are not on the hour — India is UTC+5:30, Nepal is UTC+5:45, and parts of Australia use UTC+9:30 or UTC+10:30.
