  RegularTimePeriod.getFirstMillisecond(Calendar)
- equals
  
  public boolean equals(Object obj)
  
  Tests the equality of this object against an arbitrary Object.
  This method will return true ONLY if the object is a Second object representing the same second as this instance.
  
  Overrides:
  
  equals in class Object
  
  Parameters:
  
  obj - the object to compare (null permitted).
  
  Returns:
  
  true if second and minute of this and the object are the same.

  Specified by:
  
  compareTo in interface Comparable
  
  Parameters:
  
  o1 - the object to compare.
  
  Returns:
  
  negative == before, zero == same, positive == after.
- parseSecond
  
  public static Second parseSecond(String s)
  
  Creates a new instance by parsing a string. The string is assumed to be in the format "YYYY-MM-DD HH:MM:SS", perhaps with leading or trailing whitespace.
