00:00:00
This page shows the current moment live, refreshed a few times a second, in every format developers reach for — the Unix timestamp in seconds and milliseconds, ISO 8601 in UTC and your local zone, the RFC 1123 UTC string, and your locale's date and time. Click any value to copy it, or hit Pause to freeze everything so you can copy a consistent instant. The clock reads your device's own time and runs entirely in your browser.
A Unix timestamp (or epoch time) is the number of seconds that have elapsed since 00:00:00 UTC on 1 January 1970, not counting leap seconds. It's a compact, time-zone-independent way to represent an instant. Many systems use milliseconds instead — that's the same count times 1000, which is what JavaScript's Date.now() returns.
It's exactly as accurate as your device's clock — the values come from your operating system, not a server, so nothing is uploaded. If you need atomic precision, sync your device clock to an NTP source; for everyday development the reading here is more than close enough.
UTC (Coordinated Universal Time) is the global reference with no daylight-saving offset. Local time is UTC shifted by your time zone's offset, shown here next to your zone name (for example UTC+02:00). The Unix timestamp is the same number worldwide; only the human-readable date and time differ by zone.
The values tick continuously, so the seconds and milliseconds you see and the ones you copy could differ by a moment. Pause freezes every format on a single instant, so a timestamp, an ISO string, and a local time you copy all describe exactly the same moment.
