/*
This executes every 2 hours
The intervals start at 1 am

Meaning the times it will execute will be:

      This is the given starting time
                     |
                     V
..., 21:00, 23:00, 1:00, 3:00, 5:00, 7:00, ...

The interval will not wait until the current time has reached the starting time to execute the callback function. The closest interval will be used as the time to execute the function.

Example:

Current time: 22:34

   Execution time    Starting time
              |      |
              V      V
..., 21:00, 23:00, 1:00, 3:00, 5:00, 7:00, ...

The callback function will be executed at 23:00 in this example
