UTC Offset Guide

UTC offsets are useful references, but city-based time zones are safer for real meetings because they handle daylight saving rules.

Offset Basics

UTC+8 means eight hours ahead of UTC. UTC-5 means five hours behind UTC.

City Zones

Use America/New_York or Europe/London instead of EST or GMT when daylight saving might apply.

Technical Logs

For logs, deadlines, and incident reports, UTC avoids many local-time misunderstandings.
