On the main page of MoHPC here, look under the heading, "the Classics", and then click on the description of the HP-45. It has a paragraph describing the timer function and how to control it.
If you wish to tinker, the main page's Collecting & Using Section has a pointer to the article on "Adding a Crystal to the HP-45".
Have fun!
