In this work, we present a transit timing variation analysis for 20 hot Jupiter systems, which we interpret with theoretical tidal dissipation models. For the majority of the sample, we conclude that a constant orbital period model represents the timing data best. Only WASP-12 b, TrES-1 b and WASP-121 b exhibit a changing orbital period, according to the most up-to-date results. We updated the orbital decay rate of WASP-12 b to P^{dot} = 29.4 ± 4.0 ms yr-1 and the corresponding stellar tidal quality factor to Q'_{*} = 1.72 ± 0.18 × 10^5. For TrES-1 b, the median quadratic model suggests a period decrease at a rate of −14.9 ± 0.6 ms yr−1, but the corresponding Q'_{*} = 570 ± 60 does not agree with the theoretical estimates, which suggest Q'_{*} ~ 10^6 due to internal gravity wave dissipation. Lastly, WASP-121 b exhibits orbital growth at a rate of 15.1 ± 0.8 ms yr−1, and theoretical results support outward migration due to strong inertial wave dissipation.
