Temporal.ZonedDateTime.prototype.toPlainDateTime()

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 toPlainDateTime() method of Temporal.ZonedDateTime instances returns a new Temporal.PlainDateTime object representing the date and time portions of this date-time. Only the time zone information is removed.

Warning: After a Temporal.ZonedDateTime is converted to Temporal.PlainDateTime, 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

toPlainDateTime()

Parameters

None.

Return value

A new Temporal.PlainDateTime object representing the date and time portions of this date-time.

Examples

Using toPlainDateTime()

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