Frequently Asked Questions
How many timezones are supported?+
All IANA timezone database entries — 600+ named timezones covering every inhabited place in the world.
Does it handle Daylight Saving Time?+
Yes. The browser's Intl API uses the IANA database which includes all DST rules. Conversions account for clock changes automatically.
What is UTC offset?+
UTC+X means the timezone is X hours ahead of Coordinated Universal Time. UTC−5 is 5 hours behind UTC.
Is it real-time?+
Yes. Change any input and the result updates instantly without a page reload.
Does it adjust for DST automatically?+
Yes. The tool uses the browser's timezone database which includes current DST rules for all supported zones.
Why is UTC recommended for server logs?+
UTC never observes Daylight Saving Time, so timestamps are unambiguous. Local-time logs create duplicate or missing hours when clocks change.
