Temporal.PlainTime.prototype.subtract()

The subtract() method of {{jsxref("Temporal.PlainTime")}} instances returns a new Temporal.PlainTime object representing this time moved backward by a given duration (in a form convertible by {{jsxref("Temporal/Duration/from", "Temporal.Duration.from()")}}), wrapping around the clock if necessary.

If you want to subtract two times and get a duration, use {{jsxref("Temporal/PlainTime/since", "since()")}} or {{jsxref("Temporal/PlainTime/until", "until()")}} instead.

Syntax#

subtract(duration)

Parameters#

• duration
• : A string, an object, or a {{jsxref("Temporal.Duration")}} instance representing a duration to subtract from this time. It is converted to a Temporal.Duration object using the same algorithm as {{jsxref("Temporal/Duration/from", "Temporal.Duration.from()")}}.

Return value#

A new Temporal.PlainTime object representing the time specified by the original PlainTime, minus the duration.

Subtracting a duration is equivalent to adding its negation, so all the same considerations apply.

Examples#

Subtracting a duration#

const start = Temporal.PlainTime.from("12:34:56");
const end = start.subtract({ hours: 1, minutes: 30 });
console.log(end.toString()); // 11:04:56

For more examples, see {{jsxref("Temporal/PlainTime/add", "add()")}}.
