  Returns:
    the new rounded date

### getEvenHourDateBefore

  Returns a date that is rounded to the next even minute above the given date.

  For example an input date with a time of 08:13:54 would result in a date with the time of 08:14:00. If the date's time is in the 59th minute, then the hour (and possibly the day) will be promoted.

  Parameters:
    `date` - the Date to round, if `null` the current time will be used
  Returns:
    the new rounded date

### getEvenMinuteDateBefore

    public static Date getEvenMinuteDateBefore(Date date)

  Returns a date that is rounded to the previous even minute below the given date.

  For example an input date with a time of 08:13:54 would result in a date with the time of 08:13:00.

  Parameters:
    `date` - the Date to round, if `null` the current time will be used
  Returns:
    the new rounded date

### getEvenSecondDate

    public static Date getEvenSecondDate(Date date)

  Returns a date that is rounded to the next even second above the given date.

  Parameters:
    `date` - the Date to round, if `null` the current time will be used
  Returns:
    the new rounded date

### getEvenSecondDateBefore

    public static Date getEvenSecondDateBefore(Date date)

  Returns a date that is rounded to the previous even second below the given date.

  For example an input date with a time of 08:13:54.341 would result in a date with the time of 08:13:00.000.

  Parameters:
    `date` - the Date to round, if `null` the current time will be used
  Returns:
    the new rounded date

### getNextGivenMinuteDate

    public static Date getNextGivenMinuteDate(Date date,

  Returns a date that is rounded to the next even multiple of the given minute.

  For example an input date with a time of 08:13:54, and an input minute-base of 5 would result in a date with the time of 08:15:00. The same input date with an input minute-base of 10 would result in a date with the time of 08:20:00. But a date with the time 08:53:31 and an input minute-base of 45 would result in 09:00:00, because the even-hour is the next 'base' for 45-minute intervals.

### computeFireTimes

    public static List computeFireTimes(Trigger trigg,
                                        Calendar cal,
                                        int numTimes)

  Returns a list of Dates that are the next fire times of a `Trigger`. The input trigger will be cloned before any work is done, so you need not worry about its state being altered by this method.

  Parameters:
    `trigg` - The trigger upon which to do the work
    `cal` - The calendar to apply to the trigger's schedule
    `numTimes` - The number of next fire times to produce
  Returns:
    List of java.util.Date objects

### computeFireTimesBetween

    public static List computeFireTimesBetween(Trigger trigg,

                                               Date from,
                                               Date to)

  Returns a list of Dates that are the next fire times of a `Trigger` that fall within the given date range. The input trigger will be cloned before any work is done, so you need not worry about its state being altered by this method.

  NOTE: if this is a trigger that has previously fired within the given date range, then firings which have already occured will not be listed in the output List.

  Parameters:
    `trigg` - The trigger upon which to do the work
    `cal` - The calendar to apply to the trigger's schedule
    `from` - The starting date at which to find fire times
    `to` - The ending date at which to stop finding fire times
  Returns:
    List of java.util.Date objects

### translateTime

  Translate a date & time from a users timezone to the another (probably server) timezone to assist in creating a simple trigger with the right date & time.

  Parameters:
    `date` - the date to translate
    `src` - the original time-zone
    `dest` - the destination time-zone
  Returns:
    the translated date

### getOffset

    public static int getOffset(long date,
                                TimeZone tz)

  Gets the offset from UT for the given date in the given timezone, taking into account daylight savings.

  Equivalent of TimeZone.getOffset(date) in JDK 1.4, but Quartz is trying to support JDK 1.3.

  Parameters:
    `date` - the date (in milliseconds) that is the base for the offset
    `tz` - the time-zone to calculate to offset to
  Returns:
    the offset

### getDSTSavings

    public static int getDSTSavings(TimeZone tz)

  Equivalent of TimeZone.getDSTSavings() in JDK 1.4, but Quartz is trying to support JDK 1.3.
