The until() method of Temporal.PlainTime instances returns a new Temporal.Duration object representing the duration from this time to another time (in a form convertible by Temporal.PlainTime.from()). The duration is positive if the other time is after this time, and negative if before.

This method does other - this. To do this - other, use the since() method.

Syntax

until(other)
until(other, options)

Parameters

other

A string, an object, or a Temporal.PlainTime instance representing a time to subtract this time from. It is converted to a Temporal.PlainTime object using the same algorithm as Temporal.PlainTime.from(). It must have the same calendar as this.

options Optional

The same options as since().

Return value

A new Temporal.Duration object representing the duration from this time until other. The duration is positive if other is after this time, and negative if before.

Exceptions

RangeError

Thrown if any of the options is invalid.

Examples

Using until()

const lunchTime = Temporal.PlainTime.from("12:30:00");
const now = Temporal.Now.plainTimeISO();
const duration = now.until(lunchTime);
console.log(`It will be ${duration.toLocaleString("en-US")} until lunch`);
// Example output: "It will be 3 hr, 42 min, 21 sec, 343 ms, 131 μs, 718 ns until lunch"

For more examples, see since().
