Frequently asked questions

How do I tell seconds from milliseconds?

A current timestamp in seconds has 10 digits; in milliseconds it has 13. DO101 checks the magnitude and tells you which it assumed.

What is the Unix epoch?

00:00:00 UTC on 1 January 1970. A Unix timestamp counts the seconds elapsed since that moment, ignoring leap seconds.
