Question 1

How accurate is the time?

Accepted Answer

The time is synchronized to your device's internal clock and is rendered natively by your browser's internationalization API (Intl.DateTimeFormat). It is as accurate as your system clock.

Question 2

Does it adjust for Daylight Saving Time (DST)?

Accepted Answer

Yes. By using proper IANA timezone names (like America/New_York instead of EST), the browser automatically calculates and applies the correct active Daylight Saving Time shifts for any given date.

Question 3

Is this checking a server?

Accepted Answer

No. All calculations are performed 100% locally on your machine. This page will tick perfectly even if you lose your internet connection.
