==Pass negative values to these methods. Date starts with 0, January, and subtracts. Thus, a value of �1 is the same as saying December of the previous year.==



<source lang="java">

package{
import flash.display.Sprite;

public class Main extends Sprite{
public function Main(){
var dSometime:Date = new Date(2003, 5, 23); // June 23, 2003

==Send the Date constructor a series of values for the year, month, day of the month, hour, minute, second, and millisecond to represent.==



<source lang="java">

package{
import flash.display.Sprite;

public class Main extends Sprite{
public function Main(){

public class Main extends Sprite{
public function Main(){
var dSometime:Date = new Date();
dSometime.setFullYear(5); // Set the year to 5
}

}
</source>

==Setting the Date: use the setDate() and setUTCDate() methods to set the day of the month for a Date object.==



<source lang="java">

package{
import flash.display.Sprite;

public class Main extends Sprite{
public function Main(){
var dSometime:Date = new Date(2003, 5, 23); // June 23, 2003

dSometime.setDate(23);
var dSometime:Date = new Date(3433, 1, 8);
dSometime.setDate(29);
var dSometime:Date = new Date(3433, 1, 8);
dSometime.setDate(-1);
dSometime.setMonth(-1);

}

dSometime.setSeconds(5);
dSometime.setMilliseconds(900);
trace(dSometime.toString());
dSometime.setMilliseconds(1000);

dSometime.setSeconds(5); // Set the seconds value back to 5
dSometime.setMilliseconds(-1); // 05:30:04:999

==Setting the Month==



<source lang="java">

package{
import flash.display.Sprite;

public class Main extends Sprite{

dSometime.setMonth(0); // Set the month to 0, January

var dSometime:Date = new Date(2003, 5, 23); // June 23, 2003
dSometime.setMonth(12); // January 23, 2004

}
}
}

==Setting the Time==



<source lang="java">

package{
import flash.display.Sprite;

public class Main extends Sprite{
public function Main(){
var dOriginal:Date = new Date();
var dCopy:Date = new Date(dOriginal.getTime());

var dOriginal:Date = new Date();
var dCopy:Date = new Date();
dCopy.setTime();
}
}
}
</source>

==The toString() method is inherited from the Object class, and it returns a string representing the value.==



<source lang="java">

package{
import flash.display.Sprite;

public class Main extends Sprite{
public function Main(){
trace(new Date());
}
}
}
</source>

==Use an array of the proper names to translate directly==



<source lang="java">

package{
import flash.display.Sprite;

public class Main extends Sprite{
public function Main(){
var timeOfWriting:Date = new Date(2007, 0, 28, 14, 36, 42, 16);
var daysOfWeek:Array = ["Sunday", "Monday", "Tuesday",
"Wednesday", "Thursday",
"Friday", "Saturday"];
trace(daysOfWeek[timeOfWriting.day]);
}
}
}
</source>

==Use four digit to construct the year field==



<source lang="java">

package{
import flash.display.Sprite;

public class Main extends Sprite{
public function Main(){
var dWhen:Date = new Date(1978, 9, 13);
trace(dWhen.getFullYear()); // Displays: 1978

var dThen:Date = new Date(1779, 6, 4);
trace(dThen.getFullYear()); // Displays: 1779

}
}
}
</source>

==Use getUTCFullYear() to determine the UTC year that corresponds to a given local date==



<source lang="java">

package{
import flash.display.Sprite;

public class Main extends Sprite{
public function Main(){
var dThen:Date = new Date(1964, 11, 31, 20, 0, 0, 0);
trace(dThen.getUTCFullYear());
}
}
}
</source>

==Use the getDate() and getUTCDate() methods to return the values of the local day of the month and the corresponding day of the month UTC, respectively.==



<source lang="java">

package{
import flash.display.Sprite;

public class Main extends Sprite{
public function Main(){
var dThen:Date = new Date(1523, 3, 13);
trace(dThen.getDate()); // Displays: 13
}
}
}
</source>

==Use UTC method to construct date object==



<source lang="java">

package{
import flash.display.Sprite;

public class Main extends Sprite{
public function Main(){
var dLocal:Date = new Date();
dLocal.setUTCFullYear(1970);
dLocal.setUTCMonth(0);
dLocal.setUTCDate(1);
dLocal.setUTCHours(0);
dLocal.setUTCMinutes(0);
dLocal.setUTCSeconds(0);
dLocal.setUTCMilliseconds(0);

//using the UTC() method, you could write the same thing in this way:

var nUTCDate:Number = Date.UTC(1970, 0, 1);
var dLocal:Date = new Date(nUTCDate);
}
}
}
</source>

==using the Date class"s static parse() method.==



<source lang="java">

package{
import flash.display.Sprite;

public class Main extends Sprite{
public function Main(){
trace(Date.parse("1/1/1970")); // 28800000
}
}
}
</source>

==UTC() is a method that returns the time value in milliseconds from midnight on January 1, 1970==



<source lang="java">

package{
import flash.display.Sprite;

public class Main extends Sprite{
public function Main(){
// The UTC() method takes the same arguments as the Date constructor: year, month, date, hour, minutes, seconds, milliseconds.
var nUTCDate:Number = Date.UTC(1970, 0, 1, 0, 0, 0);

var nUTCDate:Number = Date.UTC(1970, 0, 1);
}
}
}
