Frequently Asked Questions
Does it handle both seconds and milliseconds timestamps?
Yes - it automatically detects whether your input is a 10-digit (seconds) or 13-digit (milliseconds) timestamp and converts it correctly.
What timezone is the converted date shown in?
It displays the result in your browser's local timezone by default, alongside the UTC value, so you can compare both.
Can I convert a date far in the past or future?
Yes, standard Unix timestamp math (seconds since Jan 1, 1970 UTC) works correctly for a very wide range of past and future dates.
