FAQ
How do I tell seconds vs milliseconds?
Typically ~10 digits is seconds and 13 digits is milliseconds. This tool auto-detects by length.
What does "Assume UTC" mean?
It interprets timezone-less date strings (e.g. 2024-01-01 00:00:00) as UTC instead of local time.
Is my data sent to a server?
No. Everything runs locally in your browser and nothing is uploaded.
