Help needed on Schedular Services

I am trying to write a schedular service which checks for acknowledgements for Create Orders and Cancel Orders in TN database. If for any Create or Cancel there is delay for 60 mins in sending the ack then it will mail our TN Partner the corresponding info abt the create/cancel order number for that ack. I am using Trading Networks 6.0.1 and IS 6.0.1.
Any Ideas will be greatly appreciated.
