Is there way to delete all rows where user ID is duplicate for that particular day to show it like this....

Date: User ID:
02/11/2015 9:02 1283577
02/11/2015 9:03 1006768
02/11/2015 9:10 1284033
02/11/2015 9:11 1006824
02/11/2015 9:11 1284033
02/11/2015 9:12 1006824
02/11/2015 9:28 45838

Is there way to do this?

Any help would be appreciated
