Common Mistakes

Confusing Seconds with Milliseconds

✓

Unix timestamps in seconds are 10 digits long. Milliseconds are 13 digits. The tool attempts to auto-detect, but be aware of the difference.

Ignoring Timezones

✓

Epoch timestamps are always in UTC. When converting to human dates, be sure you understand if the output is showing UTC or your local browser timezone.
