If you are in fact running OH 3.x then there are no requisites for this rule template.
If you are running OH 4.x+, you are on the wrong posting. See Time Based State Machine [4.0.0.0;4.9.9.9] which has a section that discusses the prequisits. At a high level, the JS Scripting add-on, a certain version of the helper library (which comes with the add-on so you don’t have to worry about it unless you’ve installed the openhab-js manually), and a certain version or above for openhab-rules-tools which can be installed through openhabian-config or by running npm manually.
