// @recomp Patch a float that's used to render the clock into the correct value.
// This is done this way instead of patching the function to avoid conflicts with mods that need to patch the function.
// The original code is `Matrix_RotateZF(-(timeInSeconds * 0.0175f) / 10.0f, MTXMODE_APPLY);`, where 0.0175f is being used
// to convert degrees to radians. However, the correct value is PI/180 which is approximately 0.0174533f, and the difference is enough
// to cause the clock to overshoot when reaching an hour mark.
