Timestamp Converter
Current Unix time
Epoch (Unix) time is the number of seconds (not milliseconds) since 1970-01-01 00:00:00 GMT (UTC). Values update in your browser.
Enter milliseconds/seconds
Whole numbers are seconds since 1970-01-01 UTC, except large integers with |n| ≥ 1e11 (100 billion), which are read as milliseconds. Decimals count as seconds. Convert shows UTC (ISO), local time, and Unix seconds/milliseconds. All in your browser.
Enter ISO-style
Use ISO 8601-style text (for example 2024-06-01T12:00:00Z for UTC, or 2024-06-01 for date-only — meaning depends on the browser). Other strings may parse in some environments but are not guaranteed. Output is whole Unix seconds (fractional seconds truncated).
