Frequently Asked Questions

How accurate is the World Clock and does it adjust for Daylight Saving Time (DST)?
The World Clock uses your device native Intl.DateTimeFormat engine combined with authoritative IANA timezone databases and countries-and-timezones tables. It automatically calculates Daylight Saving Time (DST) shifts for any city worldwide with second-level precision.
How does the interactive time zone meeting planner work?
Switch to the Converter tab to drag the global timeline scrubber. As you scrub hours or change the reference date, all added city clocks update simultaneously with color-coded badges indicating normal business working hours (9 AM - 5 PM), evening hours, or overnight sleep periods.
Can I search and track multiple custom cities simultaneously?
Yes. Use the live city search to locate thousands of international metropolitan areas, or click curated hub presets (Global 12, Finance Capitals, US Tech Hubs, European Centers, Asia-Pacific) to load synchronized time clusters instantly.
Does the World Clock require an internet connection after loading?
Once loaded, the World Clock runs entirely client-side using browser time APIs and offline timezone offset tables, allowing continuous multi-city tracking without ongoing network polling.
