Frequently Asked Questions

How should I schedule a cross-timezone meeting?
Three steps: fix an anchor instant in UTC → have each participant confirm in their local zone → state the timezone explicitly in the invite (or annotate UTC). The side-by-side view instantly exposes conflicts like "10 a.m. in Shanghai is 10 p.m. the previous night in New York".
Are UTC, GMT, and Z the same thing?
Colloquially interchangeable. Strictly, GMT is the astronomical legacy based on Earth’s rotation; UTC is the atomic-clock standard with leap-second corrections; Z is the aviation/military spelling of UTC. In code, standardize on UTC and ignore the physical distinction.
What are the classic daylight-saving pitfalls?
Three: spring-forward times (2:30 a.m.) do not exist; fall-back times occur twice; and regions occasionally abolish DST, creating ambiguous history. The takeaway: store UTC plus a timezone identifier (America/New_York), never a fixed local offset.
