How Long Since? is a tool for finding the time that has elapsed since a particular date-time; you set the name of the event, its description, and the exact date and time on which the event occurred. Clicking a given event in the listbox, you'll be presented with time elapsed since that date. This value updates each second. You can delete a particular item by double-clicking it in the listbox. When entering the time component of the DateTime of an event you're about to save, simply enter the time as it would be in the local time used by your PC. The program will convert this to UTC, and any items in the listbox that you click upon will show the UTC version of the time.
