The toString() method of Temporal.PlainDate instances returns a string representing this date in the RFC 9557 format.

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().

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

The Temporal.PlainYearMonth.compare() static method returns a number (-1, 0, or 1) indicating whether the first year-month comes before, is the same as, or comes after the second year-month. It is equivalent to comparing their underlying ISO 8601 dates. Two year-months from different calendars may be considered equal if they start on the same ISO date.

The setHours() method of Date instances changes the hours, minutes, seconds, and/or milliseconds for this date according to local time.

The getFloat16() method of DataView instances reads 2 bytes starting at the specified byte offset of this DataView and interprets them as a 16-bit floating point number. There is no alignment constraint; multi-byte values may be fetched from any offset within bounds.

The toISOString() method of Date instances returns a string representing this date in the date time string format, a simplified format based on ISO 8601, which is always 24 or 27 characters long (YYYY-MM-DDTHH:mm:ss.sssZ or ±YYYYYY-MM-DDTHH:mm:ss.sssZ, respectively). The timezone is always UTC, as denoted by the suffix Z.

The setUTCMinutes() method of Date instances changes the minutes for this date according to universal time.
