Syntax

dateObj.valueOf()

Return value

Description

This method is functionally equivalent to the Date.prototype.getTime() method.

This method is usually called internally by JavaScript and not explicitly in code.

Examples

Using valueOf()

var x = new Date(56, 6, 17);
var myVar = x.valueOf();      // assigns -424713600000 to myVar
