FAQ

Seconds vs milliseconds?
10-digit seconds vs 13-digit milliseconds are auto-detected, with manual unit toggle to avoid the classic 1000x pitfall.
How are timezones handled?
Local browser timezone by default plus UTC display — clearer for cross-timezone debugging.
How do I get the current timestamp?
One click grabs the current timestamp in both seconds and milliseconds for code and logs.
