Frequently Asked Questions
How accurate is the time shown on ExactTimeHub?
Every clock on this site is calculated live in your browser using your device's clock and the official IANA time zone database, the same source used by most operating systems and web browsers, so it reflects the correct local time and current Daylight Saving Time status for each city.
Does ExactTimeHub account for Daylight Saving Time automatically?
Yes. Because times are calculated from the official time zone identifier for each city (for example America/New_York) rather than a fixed offset, Daylight Saving Time transitions are applied automatically without any manual adjustment.
Can I compare two cities' time zones side by side?
Yes, use the time zone converter tool on this page or visit any of our dedicated city-to-city converter pages to see both local times, the date, and the exact hour difference at a glance.
Why do some cities show a 30 or 45 minute offset?
A handful of regions, including India, Iran, Nepal, and parts of Australia, use offsets that aren't a whole number of hours relative to UTC. This is a deliberate national choice, usually to sit between two whole-hour options.
