Temporal.ZonedDateTime.prototype.toPlainTime()

The toPlainTime() method of ZonedDateTime instances returns a new 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

toPlainTime()

Parameters

None.

Return value

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

Examples

Using toPlainTime()

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
