The date shown in windows by default is the modification date again this does not reflect on the date the game was made if you hit properties you can see a creation dates and other dates but these all reflect on the file itself and still nothing to do with when the game was made
Not sure if those are GBA or DS games but whatever those are may have dates set in the headers that would be dates of when the game was made (those dates may be earlier than the release dates of the games though)
At the end of the day those dates don't have any importance at all
