Auto treats numbers below 1,000,000,000,000 as seconds. Choose Seconds or Milliseconds when a short value could mean either.
How to Use
- Read the current timestamp, or paste a value of your own.
- Leave the unit on Auto or force seconds or milliseconds.
- Enter a calendar time and time zone to convert the other way.
- Copy the result, insert the current time with Now, or reset the form.
FAQ
How does Auto tell seconds from milliseconds?
Values below 1,000,000,000,000 are treated as seconds. Choose Seconds or Milliseconds when a short value could mean either.
Are negative timestamps allowed?
Yes. Values outside the range JavaScript dates can represent are rejected with an error.
Does the time zone include daylight saving?
Yes. Conversions use the selected IANA time zone, so summer and winter offsets differ where that zone observes them.
