To reset time , turn on then with the pin touch the edit icon in lower right corner hold for several seconds , this will bring up the header for the day and state ,touch the enter and it will go to next line which is date and time there you can change it. easy after doing it a few times. if all else fails turn it one and reset it from the hole in the rear and start over , but remember when you do this you'll loose you saved information . hope this helps
