Some functions, like rebalance() in RebalanceManagerV3 use _deadline as a time limit for swapExactTokensForTokens()
Other functions, like _joinTokenSingle() of SingleTokenJoinV2.sol and _exit() of SingleNativeTokenExitV2() use block.timestamp, although a deadline field is present in the struct.
Possibly the deadline fields should have been used.
RebalanceManagerV3.sol L158-L203
RebalanceManagerV3.sol L63-L104
SingleTokenJoinV2.sol L80-L112
SingleNativeTokenExitV2.sol L59-L88
Check whether the deadline fields should have been used. If so replace block.timestamp with the appropriate deadline
