Frequently asked questions
- What is a Unix timestamp?
- It is the number of seconds or milliseconds elapsed since January 1, 1970 UTC, and it is the standard way computers store points in time.
- How does the tool know if my number is seconds or milliseconds?
- Values below 100 billion are treated as seconds and multiplied by 1000 automatically, while larger values are read as milliseconds. Both 1728700000 and 1728700000000 work.
- What time zone is used for the output?
- Dates are shown in your own browser's local time zone, so the same timestamp can appear differently on computers in different regions.
- How do I convert a date to a timestamp?
- Type the date into the Date to Timestamp field in YYYY-MM-DD HH:MM:SS format and the Unix value in seconds appears below.
