Your query already selects none duplicates because your using the DISTINCT keyword. You will not get duplicates using that keyword nor would you if you used UNIQUE. you could just get the last item and the date of today and use php to check the date difference.
get last item using id column
the last method requires a proper date data type like DATETIME or TIMESTAMP and does not work on any VARCHAR types.
Your array would then have three values year, month, and day which you can use php's built in date function to get these for the current day and subtract the values to see the time elapsed.
just giving you options to get todays date with code and compare your last entries date.
