Understand the results
Why choose a city or IANA zone instead of a fixed UTC offset?
An offset such as UTC+01:00 has no calendar rules. An IANA zone identifies the rules for a place on the chosen date, including seasonal changes. A country can have several zones; verify the specific place in the city directory.
What if a local time is skipped or repeated?
When clocks move forward, some local times do not exist; GlobeTime asks you to choose another time. When clocks move back, one local reading may identify two instants; choose the first or second occurrence. Check the date in the time converter.
Why can a day differ from 24 elapsed hours?
A civil date counts calendar boundaries; elapsed time counts instants. A daylight saving transition can make a local day 23 or 25 hours. For counting and adding dates, use the date calculator.
How do ticket dates and travel duration relate?
Departure and arrival are written in each place's local time. The arrival can show an earlier date after crossing the date line, while the real duration remains positive. Enter both zones in the arrival time calculator.
Links and privacy
Are shared plans private or saved?
The plan is encoded in the URL so another person can reopen it; anyone with that URL can read its settings. GlobeTime does not store the plan in an account. Avoid putting sensitive information in a shared link. Try the meeting planner.
