Temporal.ZonedDateTime.prototype.toPlainTime()

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The toPlainTime() method of Temporal.ZonedDateTime instances returns a new Temporal.PlainTime object representing the time portion of this date-time.

Warning: After a Temporal.ZonedDateTime is converted to Temporal.PlainTime, it's no longer time-zone-aware. Subsequent operations like arithmetic or with() operations will not adjust for DST and may not yield the same results as equivalent operations with the original Temporal.ZonedDateTime. However, unless you perform those operations across a time zone offset transition, it's impossible to notice the difference. Therefore, be very careful when performing this conversion because subsequent results may be correct most of the time, but only turn out incorrect when moving across offset transitions like when DST starts or ends.

Syntax

js
toPlainTime()

Parameters

None.

Return value

A new Temporal.PlainTime object representing the time portion of this date-time.

Examples

Using toPlainTime()

js
const zdt = Temporal.ZonedDateTime.from(
  "2021-07-01T12:34:56.987654321-04:00[America/New_York]",
);
const plainTime = zdt.toPlainTime();
console.log(plainTime.toString()); // 12:34:56.987654321
