The year accessor property of Temporal.PlainDateTime instances returns an integer representing the number of years of this date relative to the start of a calendar-specific epoch year. It is calendar-dependent.

The setFloat16() method of DataView instances takes a number and stores it as a 16-bit floating point number in the 2 bytes starting at the specified byte offset of this DataView. There is no alignment constraint; multi-byte values may be stored at any offset within bounds.

The setInt32() method of DataView instances takes a number and stores it as a 32-bit signed integer in the 4 bytes starting at the specified byte offset of this DataView. There is no alignment constraint; multi-byte values may be stored at any offset within bounds.

The getUint32() method of DataView instances reads 4 bytes starting at the specified byte offset of this DataView and interprets them as a 32-bit unsigned integer. There is no alignment constraint; multi-byte values may be fetched from any offset within bounds.

The setInt16() method of DataView instances takes a number and stores it as a 16-bit signed integer in the 2 bytes starting at the specified byte offset of this DataView. There is no alignment constraint; multi-byte values may be stored at any offset within bounds.

The setFloat32() method of DataView instances takes a number and stores it as a 32-bit floating point number in the 4 bytes starting at the specified byte offset of this DataView. There is no alignment constraint; multi-byte values may be stored at any offset within bounds.

The monthsInYear accessor property of Temporal.ZonedDateTime instances returns a positive integer representing the number of months in the year of this date. It is calendar-dependent.

The round() method of Temporal.Instant instances returns a new Temporal.Instant object representing this instant rounded to the given unit.

The era accessor property of Temporal.PlainDateTime instances returns a calendar-specific lowercase string representing the era of this date, or undefined if the calendar does not use eras (e.g., ISO 8601). era and eraYear together uniquely identify a year in a calendar, in the same way that year does. It is calendar-dependent.

The round() method of Temporal.PlainTime instances returns a new Temporal.PlainTime object representing this time rounded to the given unit.
