When I do ps -ef, I see "TIME" field. What does this field mean? From what I understand, this tells the actual CPU time, that the process got (amidst all the context switching). Does the TIME field include the disk read/write time also or only the CPU time?

It's the execution time - the time the process actually used the CPU(s), this does not count in the time the process waits for I/O events.
man ps,/time, first result.
