Calculating the time dilation for an object inside a black hole returns imaginary values, does this have a deeper meaning?

Or is it just a quirk of the math? Probably doesn't mean anything because no outside observer can see any objects crossing over the event horizon anyways, but it's still interesting. Using the t0 = t1 * sqrt(1 - GM/rc²) formula for non-rotating spherical masses.

The Schwarzschild coordinate chart does not cover the region beyond the event horizon. To the faraway observer, the inside region doesn't even exist. It doesn't make any sense to talk about the time dilation factor between a faraway observer and an observer beyond the horizon.
