    DurationFormatUtils instances should NOT be constructed in standard programming.
    
    This constructor is public to permit tools that require a JavaBean instance to operate.
- Method Detail
  - formatDurationHMS
```
public static String formatDurationHMS(long durationMillis)
```
    Formats the time gap as a string.
    
    The format used is ISO8601-like: H:m:s.S.

    Parameters:
    
    durationMillis - the duration to format
    
    format - the way in which to format the duration
    
    Returns:
    
    the time as a String
  - formatDuration
```

                                    boolean padWithZeros)
```
    Formats the time gap as a string, using the specified format. Padding the left hand side of numbers with zeroes is optional and the timezone may be specified.
    
    This method formats durations using the days and lower fields of the format pattern. Months and larger are not used.
    
    Parameters:
    
    durationMillis - the duration to format
    
    format - the way in which to format the duration
    
    padWithZeros - whether to pad the left hand side of numbers with 0's
    
    Returns:
    
    the time as a String
  - formatDurationWords
```
public static String formatDurationWords(long durationMillis,
                                         boolean suppressLeadingZeroElements,
                                         boolean suppressTrailingZeroElements)
```
    Formats an elapsed time into a plurialization correct string.
    
    This method formats durations using the days and lower fields of the format pattern. Months and larger are not used.
    
    Parameters:

    format - the way in which to format the duration
    
    Returns:
    
    the time as a String
  - formatPeriod
```
public static String formatPeriod(long startMillis,
                                  long endMillis,
                                  String format,
                                  boolean padWithZeros,
                                  TimeZone timezone)
```
    Formats the time gap as a string, using the specified format. Padding the left hand side of numbers with zeroes is optional and the timezone may be specified.
    
    When calculating the difference between months/days, it chooses to calculate months first. So when working out the number of months and days between January 15th and March 10th, it choose 1 month and 23 days gained by choosing January->February = 1 month and then calculating days forwards, and not the 1 month and 26 days gained by choosing March -> February = 1 month and then calculating days backwards.
    
    For more control, the Joda-Time library is recommended.
    
    Parameters:
    
    startMillis - the start of the duration
    
    endMillis - the end of the duration
    
    format - the way in which to format the duration
    
    padWithZeros - whether to pad the left hand side of numbers with 0's
    
    timezone - the millis are defined in
    
    Returns:
    
    the time as a String

character	duration element
y	years
M	months
d	days
H	hours
m	minutes
s	seconds
S	milliseconds
