How to use
Step 1
Paste a timestamp or date string
The converter accepts Unix seconds, Unix milliseconds, ISO strings, and other date inputs that JavaScript can parse reliably.
Step 2
Read multiple output formats
Use the generated UTC, local, and Unix values to compare logs, token claims, or API payloads without switching tools.
Step 3
Use the matching format downstream
Copy the format your target system expects, whether that is seconds, milliseconds, or an ISO timestamp.
FAQ
How does the tool detect seconds vs milliseconds?
10-digit numeric input is treated as Unix seconds and 13-digit numeric input is treated as Unix milliseconds.
Why do I see both UTC and local time?
Many debugging tasks require comparing a machine-friendly UTC value with the time you see in your own locale.
Can I paste ISO timestamps here?
Yes. ISO strings and other parseable date values can be converted into Unix seconds and Unix milliseconds.
