where q is charge and t is time

Current is not derived from the relationship between charge and time, although the equation Q=I*t is still true.
The derivation of current comes from the force between 2 infinitely long conductors that are 1 metre apart in a vacuum...
One amp is the steady current, which if flowing in two parallel conductors of infinite length and one metre apart in empty space, causes each conductor to experience a force of exactly 2*10^-7 Newtons per metre of length.
This little experiment should help you...http://www.physics.upenn.edu/~uglabs/exp68_doc.pdf

That's correct. Current is how much charge flows in a unit time so it's coulombs per second.

Yep, this is right.
Current is either voltage\ resistance, or in this case the rate of change of charge.
So Amperes( A) or C/s will work.
