Gravity (gravitational field) and Time (クリ)
There is optical path of triangle ∆ABC with top A of tall tower and mirror BC placed on the ground (as vertices). Laser light emitted from light source set at A (frequency is constant) is reflected by BC and returns to A. Frequencies of laser light at ABC will be the same. There will be no time dilation due to gravity.
