## java.util
Class Date

    java.lang.Object
      java.util.Date

    @TransactionType(value=SUPPORTS)
    public class Date

extends Object

The class Date represents a specific instant in time, with millisecond precision.

This class has been subset for the Java ME based on the JDK 1.3 Date class. Many methods and variables have been pruned, and other methods simplified, in an effort to reduce the size of this class.

Although the Date class is intended to reflect coordinated universal time (UTC), it may not do so exactly, depending on the host environment of the Java Virtual Machine. Nearly all modern operating systems assume that 1 day = 24x60x60 = 86400 seconds in all cases. In UTC, however, about once every year or two there is an extra second, called a "leap second." The leap second is always added as the last second of the day, and always on December 31 or June 30. For example, the last minute of the year 1995 was 61 seconds long, thanks to an added leap second. Most computer clocks are not accurate enough to be able to reflect the leap-second distinction.

Constructor Summary
`Date()` Allocates a `Date` object and initializes it to represent the current time specified number of milliseconds since the standard base time known as "the epoch", namely January 1, 1970, 00:00:00 GMT.
`Date(long date)` Allocates a `Date` object and initializes it to represent the specified number of milliseconds since the standard base time known as "the epoch", namely January 1, 1970, 00:00:00 GMT.

Method Summary
`boolean` | `equals(Object obj)` Compares two dates for equality.
`long` | `getTime()` Returns the number of milliseconds since January 1, 1970, 00:00:00 GMT represented by this `Date` object.
`int` | `hashCode()` Returns a hash code value for this object.
`void` | `setTime(long time)` Sets this `Date` object to represent a point in time that is `time` milliseconds after January 1, 1970 00:00:00 GMT.
`String` | `toString()` Converts this `Date` object to a `String` of the form:

Constructor Detail

### Date

    public Date()

  Allocates a `Date` object and initializes it to represent the current time specified number of milliseconds since the standard base time known as "the epoch", namely January 1, 1970, 00:00:00 GMT.

  See Also:
    `System.currentTimeMillis()`

### Date

    public Date(long date)

  Allocates a `Date` object and initializes it to represent the specified number of milliseconds since the standard base time known as "the epoch", namely January 1, 1970, 00:00:00 GMT.

  Parameters:
    `date` - the milliseconds since January 1, 1970, 00:00:00 GMT.
  See Also:
    `System.currentTimeMillis()`

Method Detail

### getTime

    public long getTime()

  Returns the number of milliseconds since January 1, 1970, 00:00:00 GMT represented by this `Date` object.

  Returns:
    the number of milliseconds since January 1, 1970, 00:00:00 GMT represented by this date.
  See Also:
    `setTime(long)`

### setTime

    public void setTime(long time)

  Sets this `Date` object to represent a point in time that is `time` milliseconds after January 1, 1970 00:00:00 GMT.

  Parameters:
    `time` - the number of milliseconds.
  See Also:
    `getTime()`

### equals

    public boolean equals(Object obj)

  Compares two dates for equality. The result is `true` if and only if the argument is not `null` and is a `Date` object that represents the same point in time, to the millisecond, as this object.

  Thus, two `Date` objects are equal if and only if the `getTime` method returns the same `long` value for both.

  Overrides:
    `equals` in class `Object`
  Parameters:
    `obj` - the object to compare with.
  Returns:
    `true` if the objects are the same; `false` otherwise.
  See Also:
    `getTime()`

### hashCode

    public int hashCode()

  Returns a hash code value for this object. The result is the exclusive OR of the two halves of the primitive `long` value returned by the `getTime()` method. That is, the hash code is the value of the expression:

  >      (int) (this.getTime() ˆ (this.getTime() >>> 32))

  Overrides:
    `hashCode` in class `Object`
  Returns:
    a hash code value for this object.
  See Also:
    `Object.equals(java.lang.Object)`, `Hashtable`

### toString

    public String toString()

  Converts this `Date` object to a `String` of the form:

  >       dow mon dd hh:mm:ss zzz yyyy

  where:
  - `dow` is the day of the week (`Sun, Mon, Tue, Wed, Thu, Fri, Sat`).
  - `mon` is the month (`Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, Dec`).
  - `dd` is the day of the month (`01` through `31`), as two decimal digits.
  - `hh` is the hour of the day (`00` through `23`), as two decimal digits.
  - `mm` is the minute within the hour (`00` through `59`), as two decimal digits.
  - `ss` is the second within the minute (`00` through `61`, as two decimal digits.
  - `zzz` is the time zone (and may reflect daylight savings time). If time zone information is not available, then `zzz` is empty - that is, it consists of no characters at all.
  - `yyyy` is the year, as four decimal digits.

  Overrides:
    `toString` in class `Object`
  Returns:
    a string representation of this date.
  Since:
    CLDC 1.1
