Decode UTC Time and Date

I need a routine in Java (1.3) to decode a UTC time value which I believe is in Timer tics. The date is in IBM packed decimal. This is a timestamp coming from an IBM mainframe and the documentation is somewhat poor on the exact makeup of the field, but I have a number of samples of both and I know what the date /time "should" be. Would appreciate some help to decode these fields & create a suitable routine. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Complete ownership and distribution copyrights to all work purchased. ## Platform Windows, Linux, Java 1.3
