Kyrathasoft How Long Since? (my 2nd Coding Snacks fulfillment)

[kyrathaba]

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.

New version prevents illegal characters from being used for the short description, since the short description is used as a file-name when a historical event is saved to disk.

Also, be aware that the conversion of the time from local PC time to UTC can have the effect of shifting the day's date forward 1 day. For example, if you entered December 28, 1970 11:57 PM and saved it while running the program on a PC set to Central Standard Time, when you clicked on the saved item in the listbox, you'll see the Date and Time change to Dec. 29, 1970 5:57 AM.  Same moment in history, but the shift occurs because we've converted to UTC.

Also, be aware that one year is actually 365.25 days, which is why every 4 years is a Leap Year, and adds a 29th day to February.  So if you're watching the one-year-elapsed-time mark arrive on one of your events, you're going to see this:



"0y" doesn't change to "1y" until the Days part of the elapsed time TimeSpan  is 91.25.
