I am trying to make a countdown clock that changes based on the current time.
Example:
If it is currently between 10:00 A.M. and 10:45 A.M. then count down to 10:45 A.M.
If it is currently between 11:00 A.M. and 11:30 A.M. then count down to 11:30 A.M.
but there is no pattern. i need to be able to customize it because the time zones vary in length.
