Live Unix time
——Paste a timestamp to see ISO UTC and local time.
How to convert a Unix timestamp
See the current Unix time in seconds and milliseconds, updating every second.
Epochly auto-detects seconds vs milliseconds (and µs/ns by length) and shows ISO UTC plus your timezone.
Enter a date and time in the selected timezone to get seconds and milliseconds.
Paste many lines, review the table, copy any field. Nothing is uploaded or put in the URL.
An epoch converter that never sees your timestamps
Epochly runs entirely in your browser. Paste a Unix timestamp and it auto-detects seconds, milliseconds, microseconds or nanoseconds by digit length, then shows ISO-8601 UTC and a local string in your chosen IANA timezone via Intl. Or enter a calendar date and time in that timezone to get Unix seconds and milliseconds. Batch mode converts many lines at once. Nothing is sent to a server, nothing is logged, and values are never placed in the URL.
