Guide / 02
Quick guide
- Enter Unix seconds or milliseconds, or use the current-time button for a fresh example.
- Compare Local, UTC, and millisecond output and choose the time basis required by the receiving system.
- When converting from the date field, remember that the entered wall time is interpreted in the browser's local zone.
CHECK
Validate the result
Enter 0 and confirm that UTC points to 1970-01-01 00:00:00 and that the millisecond value is zero.
LIMITS
Know the limits
An absolute value below one trillion is treated as seconds and a larger value as milliseconds, so very distant second values can be misclassified. Display depends on the device zone and browser date range.

FAQ
Frequently asked
Why does the same timestamp show a different clock time on another computer?
The timestamp identifies the same instant, but Local output is formatted in each device's time zone. Use the UTC line for system-to-system comparisons.
