## Class TimeSelector

- java.lang.Object
- - org.apache.turbine.util.TimeSelector

-     public class TimeSelector
      extends Object

  TimeSelector is a utility class to handle the creation of a set of time drop-down menus. The code is broken into a set of static methods for quick and easy access to the individual select objects:

        ElementContainer ec timeSelect = new ElementContainer();
        String myName = "mytime";
        ec.addElement(TimeSelector.getHourSelector(myName));
        ec.addElement(TimeSelector.getMinuteSelector(myName));
        ec.addElement(TimeSelector.getAMPMSelector(myName));

  There are also methods which will use attributes to build a complete time selector in the default 12hr format (eg HH:MM am/pm):

        TimeSelector ts = new TimeSelector(myName);
        timeSelect = ts.ecsOutput();

  Minutes/Seconds are by default rounded to the nearest 5 units although this can be easily changed. 24hr TimeSelectors can also be produced. The following example creates a full precision TimeSelector (eg HH:MM:SS):

        TimeSelector ts = new TimeSelector(myName);
        ts.setTimeFormat(TimeSelector.TWENTY_FOUR_HOUR);
        ts.setMinuteInterval(1);
        ts.setSecondInterval(1);
        ts.setShowSeconds(true);
        timeSelect = ts.toString();
