Wrong.
If you leave Dubai in an acclimatized state, you remain acclimatized to Dubai even if you vacation on the other side of the planet for three weeks and return to Dubai 2 hours before your report time for SFO.
You only lose your acclimatized state if you end a duty outside the zone.
So
-be kind to yourself
-read the OM(A)
-cease perpetuating splenetic twaddle
