I have set up 2 timers on start event of a process model. First timer runs

I have set up 2 timers on start event of a process model.
First timer runs on 2nd Monday of every month.Second timer should be triggered on 9th day after first email.
I have used an expression rule to get 9 th day after 2nd Monday.But timer is getting triggered wrongly.
e.g In Sept, first email was sent on 14th. As per logic second email should be sent on 23rd Sept. But email got triggered on 19th Sept (19 value was generated in August).
Do we need to republish PM after first timer so that it takes new value for second trigger for every month?
