Showing the current time, updated every second.

How to use it

  1. Paste a timestamp (seconds, milliseconds, microseconds or nanoseconds) or a date such as 2026-10-25 12:00:00.
  2. Pick the time zone. Dates without an offset are read in that zone.
  3. Copy any row. Press “Now” (or clear the box) for the current time, updated every second.

Frequently asked questions

How does it know seconds from milliseconds?

By the number of digits: up to 11 digits is seconds, 12 to 14 milliseconds, 15 to 17 microseconds and more is nanoseconds. This covers dates from 1970 until the year 5138 in seconds.

What date formats can I paste?

ISO 8601 (2026-10-25T12:00:00Z, with or without an offset or fraction), “2026-10-25 12:00:00”, a plain date, and RFC 2822 (Sun, 25 Oct 2026 12:00:00 GMT).

What happens at daylight-saving changes?

When clocks go back and a time happens twice, the first one is used. When clocks go forward and a time does not exist, it moves forward by the missing hour.

What is the Year 2038 problem?

A signed 32-bit count of seconds runs out on 19 January 2038 at 03:14:07 UTC (timestamp 2147483647). This page uses 64-bit-safe arithmetic, so later dates work.

Is the clock accurate?

It shows your device’s clock. Nothing is requested from a server.
