The clock will run slow.

Work Step by Step

The pendulum will be slightly longer on a hot day because the brass rod expands. The period of a pendulum is proportional to the square root of its length, $T = 2 \pi \sqrt{\frac{L}{g}}$, so the period will be longer. The pendulum takes more time for one cycle, so the clock runs slow.
