I had a salesforce requirement to run anonymous apex continuosly after every 30 seconds. I implemented my idea and now instead of using batch classes I am using the third party tool made by me to run a piece of apex code at regular intervals of time. I want to sell this idea as there is no tool which does this and exists in the real world. What can be my options to sell my implementation?

I want to ask if there is a method in Salesforce for checking if a given string is a DateTime format string?
