Frequently Asked Questions

1. How does the tool know if I entered seconds or milliseconds?

A 10-digit number is treated as seconds, while a 13-digit number is treated as milliseconds — matching how Unix timestamps are typically represented.

2. What date formats can I enter?

Most common date formats are supported, such as "2026-07-30" or "July 30, 2026", along with ISO 8601 strings.

3. What timezone is the local time shown in?

The local time reflects the server's timezone setting. For a specific timezone, use the UTC or ISO value and convert manually.
