what could this number possibly represent?

we have dropped the units of distance
we have dropped the units of time

if we do associate this number with anything then
we must associate this number with a velocity.

we must give the result in m/s (distance / time)

so the time dilation equation is an equation that is
used to solve for velocity it is not used to solve
for time.
No, velocity is not what the equation solves for.

The number you are asking about is a ratio, I think, and as such it would be without units.

Once you have the ratio, you multiply it by t (in seconds) to get
the answer, t prime, which will also be in seconds--the dilated time.
