About Timezone Offsets
UTC (Coordinated Universal Time) is the primary time standard by which the world regulates clocks.
Positive offsets (+) are east of the Prime Meridian. Negative offsets (-) are west.
Half-hour offsets (like India UTC+5:30) exist because timezone boundaries don't always follow longitude lines.
The Date Line: UTC+12 and UTC-12 are 24 hours apart but geographically close, creating the International Date Line.
