time input help

[malyn]

hi guys,

I am making a program in which I have to enter start date and time and stop date and time in format like 01:05:07 15:26:57

i don’t know how to get that value from the user in hh:mm:ss format and calculate the difference between different inputs. i have no clue of that. could you guys give me some tips on that?
