Duration

A length of time, exact to the millisecond, written PT1H30M.

Time and calendar; ordered; since Jadpo 0.1.0.

Make one

text.parse(raw, as: Duration) reads one from its text; text that isn't one at all fails malformed, such as 5 minutes, P or PT.

This operation gives one: temporal.between.

Text, JSON and storage

text.from writes its canonical text, the one form text.parse reads back. JSON sends its canonical text as a string.

It is stored in one column named for the field, of type bigint. PT1H30M is stored as 5400000.

Shown to people

text.format(value, locale:) shows it to people in their locale.

With locale: Locale.en_gb:

Operations

• temporal.between(start: Instant, end: Instant) -> Duration: How long from start to end: end - start.

Like every standard type, it also has the contract's own operations: text.parse, text.from, text.format, json.read, json.write and ==. It is ordered, so < and sorting take it. Every standard type meets one contract says how they work.
