ECMAScript v1

24.32.1. Synopsis

date.getTime( )

24.32.1.1. Returns

The millisecond representation of the specified Date object datethat is, the number of milliseconds between midnight (GMT) on 1/1/1970 and the date and time specified by date.

24.32.2. Description

getTime( ) converts a date and time to a single integer. This is useful when you want to compare two Date objects or to determine the time elapsed between two dates. Note that the millisecond representation of a date is independent of the time zone, so there is no getUTCTime( ) method in addition to this one. Don't confuse this getTime( ) method with the getday( ) and getdate( ) methods, which return the day of the week and the day of the month, respectively.

Date.parse( ) and Date.UTC( ) allow you to convert a date and time specification to a millisecond representation without going through the overhead of first creating a Date object.
