Refactor code in src/middleware/admin.js to reduce cognitive complexity

[e5z26]

I changed an else and nestled if into else if on a helper function. I also removed a condition in an if (leads to adding some number to the time) by changing it into having the number times a factor (that is 0 or 1 depending on the condition) being added to the time. At the end of the code, instead of using an else, I returned on the other conditions and ran what was in the else in the body of the function. resolves #481
