The minRentalDayDivisor is defined in RCTreasury.sol and copied to each market.
The minRentalDayDivisor can be updated via setMinRental, but then it isnt updated in the already created market.
To calculate the minimum rent time, in function withdrawDeposit of RCTreasury.sol, the latest version of minRentalDayDivisor is used, which could be different than the values in the market.
