The pattern character for year is lowercase y. So, change this

DateFormat df = new SimpleDateFormat("YY-MM-HH-mm-ss", Locale.ENGLISH);

to something like

DateFormat df = new SimpleDateFormat("yyyy-MM-HH-mm-ss", Locale.ENGLISH);

(note that you seem to be missing the day-in-month there, too)

The simplest solution for this to check if the difference between current date & time values and selected date & time values.If the difference is greater than 0 then its the future time.It is the simplest solution because the return type values of datepicker and timepicker is int.It works for datepicker dialog and time picker dialog as well.
