Frequently Asked Questions
How do I know if a timestamp is in seconds or milliseconds? ▼
Timestamps with 10 digits (e.g., 1700000000) are in seconds. Timestamps with 13 digits (e.g., 1700000000000) are in milliseconds. The tool automatically detects both.
What is Epoch time? ▼
Unix Epoch time measures the total number of elapsed seconds since January 1, 1970 00:00:00 UTC, excluding leap seconds.
Does this handle my local time zone? ▼
Yes. It converts to both standard Coordinated Universal Time (UTC) and your system's local browser time zone.
