What is the best way to convert seconds into Hour Minutes Seconds Milliseconds time

Question

What is the best way to convert seconds into  Hour Minutes Seconds Milliseconds  time   Let s say I have 80 seconds  are there any specialized classes techniques in  NET that would allow me to convert those 80 seconds into  00h 00m 00s 00ms  format like to DateTime or something
