do it as d.skelton says, start buttons are in parallel (this includes the timer), stop and overload in series to break the circuit. dont forget you will need to wire a retaining contact to keep the contactor energised (also in parallel) unless you want to keep your finger on the button!!! LOL!!!

Seriously this isn't hard!

You want your DOL starter to have a timer element that switches it on and off on when programmed right?

Just wire a two channel timer in parallel from your start button and in series with your stop button. Channel 1 (n/o) to pulse the start when you want the pump on, channel 2 (n/c) to pulse open to stop when you want the pump off.

The DOL will still be able to override the timer whenever.

Thank you!
