Frequently Asked Questions
How accurate is the time displayed on World-Time.org?
The time is synchronized with atomic clock time via NTP (Network Time Protocol) and is typically accurate to within 0.02–0.10 seconds. Our system syncs with multiple stratum-1 time servers to ensure precision.
How do I change the time zone or city?
Use the search box at the top of the page to search for any city or time zone (e.g., "London", "Tokyo", "UTC+8"). You can also browse all time zones on our time zones page. Your selected time zone is saved in a cookie for your next visit.
How do I set a default location?
Navigate to any city's time page (e.g., London) and click "Set as default". The site will remember your preference and show that city's time by default on future visits. You can also enable browser geolocation for automatic detection.
Can I embed World-Time.org on my website?
Yes! Visit our widgets page to generate embeddable time widgets. You can customize the appearance and time zone, then copy the HTML/JavaScript code to your site. Widgets are free to use for personal and commercial websites.
How do I compare time between two cities?
Use our time comparison tool. Select two cities or time zones and see the current time in both locations side by side. This is useful for scheduling meetings across different time zones.
What is Daylight Saving Time (DST) and how does it affect me?
Daylight Saving Time is the practice of advancing clocks during warmer months. Our site automatically accounts for DST changes based on each time zone's observed rules. Visit our DST page to see upcoming transitions for any country or region.

How do I switch between 12-hour and 24-hour time format?
Go to the customize page and select either "12-hour (AM/PM)" or "24-hour" format. You can also change the theme (dark/light mode) and the first day of the week from the same page.
What is the current Unix timestamp?
