Glitches

I keep trying to set dates but when I hit done and save the date, the app decides to have a mind of its own and not only changes the date but also the time. I have a countdown set for August 9th at 12AM but it automatically changes to August 7th 9PM. I dont know why this keeps happening. Ive had this app for about 3 years but these updates have ruined it.
