Basically im trying to make a countdown timer to specific date, but i dont want the output to be a standard yy/mm/dd/ss format, i want it to display the number of years and the a decimal percentage, like so : 16.39872937498273 years left until blah.. and so far i have created a system clock that updates as far as milliseconds but no further..
so how to get a date to convert to year + decimal and how do you update a clock farther than milliseconds?
so far this is my code, only counts up and displays system time, i need to change it to count down and to a date.
