Hello Moolchand,

There are over thousands of colleges in India that provide diploma course and there is no standard timing for all, each college has its own time table and curriculum.So, if you can provide the name of the college then i can tell you the timing of the college.It can be in morning shift or evening shift and every brach has its own timing too so you need to be more specific so that i can help you with exact information.
If you have any doubts then you can ask me.
