Temporal.PlainTime.prototype.toJSON()
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.

The toJSON() method of Temporal.PlainTime instances returns a string representing this time in the same RFC 9557 format as calling toString(). It is intended to be implicitly called by JSON.stringify().
Syntax
toJSON()
Parameters
None.
Return value
A string representing the given time in the RFC 9557 format.
Description
The method is automatically called by JSON.stringify() when a Temporal.PlainTime object is encountered during JSON serialization. The serialized value can then be deserialized using the Temporal.PlainTime.from() function within the reviver of JSON.parse().
Examples
Using toJSON()
const time = Temporal.PlainTime.from({ hour: 12, minute: 34, second: 56 });
const timeStr = time.toJSON(); // '12:34:56'
const t2 = Temporal.PlainTime.from(timeStr);
JSON serialization and parsing
This example shows how Temporal.PlainTime can be serialized as JSON without extra effort, and how to parse it back.
const time = Temporal.PlainTime.from({ hour: 12, minute: 34, second: 56 });
const jsonStr = JSON.stringify({ time }); // '{"time":"12:34:56"}'
const obj = JSON.parse(jsonStr, (key, value) => {
if (key === "time") {
return Temporal.PlainTime.from(value);
}
return value;
});
