> 0.000000..

This is neither here nor there, but that number would be 0.

It's possible that 'time' has no minimum, but as far as I am aware the solution can be continuously extended to include 0. If not then you might as well say that the universe has existed for all time, the clocks were just running a bit slow at the start.

That is a number with significant digits. 0.00000... emphasizes the fact that it's not just close to zero, but exactly zero. 0 in a physics context can be read as "0 to one significant digit", which can be non-zero. For a real example, see discussions about the total cosmic curvature, which is 0 to some finite number of significant digits, but that doesn't let us quite be sure it's totally zero.
