Can't get iPad mini into recovery mode
If you try too many times to login with the wrong passoword, iOS will force you to wait longer and longer after each failed attempt. Your ipad is telling you that you now must wait 13,568 minutes before you can attempt another login.

If you have a beckup in itunes, you can plug the ipad into your laptop and Restore from Backup in iTunes. However, you will still need the correct password to login after restore. 

If this does not work, your only options are to wipe the iPad and start over as if new. 

You can plug in the iPad into iTunes, and hold down power and home buttons until you get a screen prompting you to plug in your iPad into iTunes. You should get a dialog box asking if you wish to Restore or Update, and you should select Restore.
You can also log into icloud.com and force a remote wipe on your iPad.
