Ok jordanhuh I guess you have a stick of mass m that you are holding up at an angle theta and it is hinged at the base and you release it and it falls to the ground. Right? So what do you want to know about it, that is, what is the question?

Have you made an attempt at a solution? Are you sure the problem is asking for the time? With non uniform speed and non constant acceleration tangentially , angularly and centripetally, and small angle for theta with vertical, the problem is not easily solved .
