Remarks

An Instant has no concept of a particular time zone or calendar: it simply represents a point in time that can be globally agreed-upon.

Equality and ordering comparisons are defined in the natural way, with earlier points on the timeline being considered "less than" later points.

The default value of this type is UnixEpoch, i.e. the instant which can be represented as 1970-01-01T00:00:00Z in the ISO calendar.
