Frequently Asked Questions
How is my timezone detected?
Your browser exposes timezone info via the Intl.DateTimeFormat API and Date object, revealing your IANA timezone and UTC offset without permissions.
Can my timezone reveal my location?
Yes. Your timezone narrows your location to a region. A mismatch between IP location and timezone can indicate VPN usage.
What is DST?
Daylight Saving Time adjusts clocks forward in warmer months. Your browser handles DST automatically. Not all regions observe it.
