Hi Everyone,
I'm building a time-clock type application and am wondering about what data types to use.
i'm wondering what data type to use for elapsed time, which is purely an amount of time

i.e., hours:mins:seconds:

for example: clock in at 3:15, clock out at 7:30, time elapsed is ....?

should the datatype should that be? ...datetime?, if not what then...?

thanks for any help with this
