Make your life easy when working with dates  timestamps and durations  Use HalDateTime from  http   sourceforge net projects haldatetime  source directory  For example you can just use it to parse your input like this   HalDateTime mydate   HalDateTime valueOf   25 12 1988     System out println  mydate         will print in ISO format  1988-12-25   You can also specify patterns for parsing and printing
