You should show what the number looks like and what it means, it doesn't take much time and this can vary. Plus, this isn't a time type if it includes days in it.
The database designers decided what the data stored would be, not Crystal, and not the people in this forum, please think your posts through and provide basic information to avoid wasting time.
If it's the number of seconds then you can use a dateadd("S") function, if it's stored as formatted periods within as in 12233005
which translates to: 12:23:30:05 then you'll convert it to a string and then parse it out:
Parse it out, as in:
whileprintingrecords;
Stringvar MyTime:=totext({table.field},0,"");
stringvar DD:= mid(MyTime,1,2);
stringvar HH:= mid(MyTime,4,2);
stringvar MM:= mid(MyTime,7,2);
stringvar SS:= mid(MyTime,10,2);
