What is a Unix epoch timestamp?

A Unix epoch timestamp is the number of seconds (or milliseconds) that have elapsed since January 1, 1970 00:00:00 UTC. It is widely used in programming for date/time storage and transmission.

How do I know if my timestamp is in seconds or milliseconds?

A 10-digit number is in seconds (e.g., 1700000000), while a 13-digit number is in milliseconds (e.g., 1700000000000). DevDash auto-detects this for you.

Can I convert a human date back to epoch?

Yes. Simply type or paste a date string and DevDash will output the corresponding Unix timestamp in both seconds and milliseconds.
