Full explanation
No. This is one of the most common gambling myths and it does not hold up. The RTP of Le Zeus is set by which of the four versions the casino runs, and that setting is constant. It does not rise on a quiet morning or drop on a busy weekend night.
Each spin is an independent, RNG-decided event. The game has no clock awareness and no memory of your session. It cannot "know" it is peak hours, and it cannot tighten up because you have been playing for two hours. Believing otherwise is the same gambler's-fallacy trap as thinking a coin is "due" to land heads.
The only RTP variation that is real is the one we keep coming back to: operator-selected versions (96.26% down to 86.27%). That is a setting you can check in the game's info screen before you play, and it is the same all day every day on a given site.
So the practical advice is unchanged. Confirm the posted RTP, pick a site running the high version, and ignore any timing theory.
Why the myth is so persistent
Timing myths survive because losing streaks feel personal and memorable. Lose on a busy Saturday night and the brain files it as "the game tightens when it is busy." Win at the same time and you forget. That selective memory builds a false rule out of ordinary variance.
The reality is duller and more reassuring: the RNG has no clock, no traffic sensor and no memory of your session. The only RTP that varies is the operator-selected version, which is constant all day. Check that figure once, pick a good site, and the time on the clock becomes irrelevant to your odds.
If you take one habit from this, make it checking the info screen rather than the clock. The RTP setting is fixed by the operator and does not respond to the hour, the day, or how long you have been spinning. The only variation that exists is the version the casino chose, and that is sitting in plain sight before your first spin.
