The getTimezoneOffset() method of Date instances returns the difference, in minutes, between this date as evaluated in the UTC time zone, and the same date as evaluated in the local time zone.

The Date.UTC() static method accepts parameters representing the date and time components similar to the Date constructor, but treats them as UTC. It returns the number of milliseconds since January 1, 1970, 00:00:00 UTC.

The getMinutes() method of Date instances returns the minutes for this date according to local time.

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

The getUTCSeconds() method of Date instances returns the seconds in the specified date according to universal time.

The getYear() method of Date instances returns the year for this date according to local time. Because getYear() does not return full years ("year 2000 problem"), it is deprecated and has been replaced by the getFullYear() method.

The toLocaleLowerCase() method of String values returns this string converted to lower case, according to any locale-specific case mappings.

The fixed() method of String values creates a string that embeds this string in a <tt> element (<tt>str</tt>), which causes this string to be displayed in a fixed-width font.

The Atomics.xor() static method computes a bitwise XOR with a given value at a given position in the array, and returns the old value at that position. This atomic operation guarantees that no other write happens until the modified value is written back.

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.
