// COMMENT:  A very quick-and-dirty way to print out the number of
//           years, months, days, hours, and seconds in a given
//           number of seconds.  The style is this program is
//           not good at all -- it can be made more efficient
//           and easier to read.  Do not use this as an example
//           for your own programs.
//
//           Usage:   TimePrinter.toString( long )
//                    TimePrinter.toStringFromDouble( long )
//
