06-feb-2004 NvE "char* name" changed to "const char* name" in all specific Clone memberfunctions
                to prevent compiler warnings on Sun.
                Memberfunction Set() of TTimeStamp used in AliEvent instead of setting the date/time
                via the TTimeStamp constructor. This is only possible with ROOT version 3.10/02 or later,
                since for earlier versions the TTimeStamp::Set memberfunctions were erroneously declared
                private.
