Retrieves the number of seconds stored in a Date object.
The getSeconds method returns an integer between 0 and 59 indicating the seconds value of the indicated Date object. A zero is returned in two situations. One is when the time is less than one second into the current minute. The other occurs when the time was not stored in the Date object when the object was created. The only way to determine which situation you have is to also check the hours and minutes for zero values. If they are all zeroes, it is nearly certain that the time was not stored in the Date object.
