cout<<(*time).show(); is outputting the value returned by show. However in the show method there is no return statement.
So it's printing garbage.
gcc gives the warning 
no return statement in function returning non-void


By the way, you may want to change your compiler http://www.cplusplus.com/forum/articles/36896/
