chore: example revert on destination chains

[BeroBurny]

Thanks to Tim for finding it!

It reverted on destination chains as the timestamp went to past time.

constructor(address _owner, uint _unlockTime) payable {
        require(
            block.timestamp < _unlockTime,
            "Unlock time should be in the future"
        );

        unlockTime = _unlockTime;
        owner = payable(_owner);
    }
