Countdown Timer

Let’s say you’re offering same-day shipping on orders placed before 3pm Monday–Friday. A user interface widget should advise customers of how long they have left to complete their order in order to take advantage of this offer.

The widget should indicate how many hours, minutes and seconds are remaining. It should count down in real-time. It should not count down on Saturdays or Sundays. The timer should automatically reset at midnight Sunday–Thursday.
