### Timestamps
Unless otherwise stated, timestamps are [Unix
timestamps](https://en.wikipedia.org/wiki/Unix_time), but measured in
milliseconds. This means, they approximate the number of milliseconds
since 1970-01-01 00:00:00.000 UTC, but disregard leap seconds so that
each day is precisely 86,400,000 milliseconds. This also means that
timestamps can repeat. Most programming languages provide timestamps in
that format natively. Throughout the specification this may be referred
to as POSIX, Unix, or just "time in milliseconds".
Unless otherwise stated, are timestamps are the number of milliseconds
elapsed since the unix epoch (1970-01-01 00:00:00 UTC), but not counting
leap seconds, so that each day is precisely 86,400,000 milliseconds.
This means that timestamps can repeat during leap seconds. Most
programming languages provide timestamps in that format natively, e.g.
[ECMAScript](https://tc39.es/ecma262/multipage/numbers-and-dates.html#sec-time-values-and-time-range).
Throughout the specification this may be referred to as POSIX,
[Unix](https://en.wikipedia.org/wiki/Unix_time), or just "time in
milliseconds".
