+/**
+ Utility class for producing strings with formatted date/time.
+
+ <p>
+ This class takes as inputs a format string and a representation of a date/time.
+ The format string controls how the output is generated.
+ </p>
+ <p>
+ Formatting characters may be repeated in order to get more detailed representations
+ of that field. For instance, the format character &apos;M&apos; is used to
+ represent the month. Depending on how many times that character is repeated
+ you get a different representation.
+ </p>
+ <p>
+ For the month of September:<br/>
+ M -&gt; 9<br/>
+ MM -&gt; 09<br/>
+ MMM -&gt; Sep<br/>
+ MMMM -&gt; September
+ </p>
+ <p>
+ The effects of the duplication vary depending on the nature of the field.
+ See the notes on the individual field formatters for details. For purely numeric
+ fields such as <code>HOUR</code> adding more copies of the designator will
+ zero-pad the value to that number of characters.
+ </p>
+ <p>
+ For 7 minutes past the hour:<br/>
+ m -&gt; 7<br/>
+ mm -&gt; 07<br/>
+ mmm -&gt; 007<br/>
+ mmmm -&gt; 0007
+ </p>
