Local Time With Seconds
A clock that explains where its time comes from
This clock displays the time supplied by your device, including seconds and the local date. It does not contact an independent time server or measure how far your computer is ahead or behind. If your device clock is five minutes fast, this display will also be five minutes fast. Use it as a readable clock for a desk, presentation or shared screen.
Choose the tool for the job
Use the stopwatch to measure an activity without a fixed end. Use the countdown timer for a fixed duration, or the date countdown for an event on a calendar. To plan a call, use the date-aware time-zone converter; a current world clock alone cannot tell you what the offset will be on a future meeting date.
How to check an unexpected time
- Compare this display with your device's clock. They should agree apart from display-update delay.
- If both show the wrong hour, check the device's time-zone setting. A correct minute with the wrong hour often points to a zone setting rather than clock drift.
- If the device itself is wrong, check its automatic date/time setting and compare against an independent source such as NIST's official U.S. time. This website cannot make that independent comparison for you.
Seconds are a display, not an accuracy certificate
The display refreshes about once a second while the browser allows it to run. A busy or hidden tab can update late. Displaying seconds does not make a browser clock suitable for official race timing or precision synchronization. For a practical explanation, read device time and clock accuracy.
Search and privacy
The city search covers the cities included in this site's list, rather than every place in the world. It uses your browser's time-zone rules and does not need location permission.
