(2.1) expressed by recharge ra. t. w = V. m /I (2.1a) If a system can be approximated by unidimensional flow pattern, this definition yields t. w = x/v. w, where x is the length for which t. w. is determined, and v. w. is the mean water velocity, defined below. Darcy’s velocity (v. f) is defined as the ratio of Q/S, S being the cross-section ...

That is, the time (or spatial) coordinate t is allowed to take on arbitrary real values (perhaps over some interval) and the value x(t) of the signal itself is allowed to take on arbitrary real values (again perhaps within some interval).
