This flow calculates the amount of time passed between 2 dates, and gives the option to save the result to a file on the internal storage. The file and directory are created on the first save, and either will be recreated if they are deleted, moved, or renamed. I've tested every possible condition so you should never see a negative result. The total days interval is found using Julian numbers converted from Gregorian calender dates, and should always be 100% accurate. Please let me know of any inconsistencies or bugs. I may add in the future time zone conversions, back options, more explicit logging, and reducing the number of blocks using dictionaries (I know there's too many blocks).
