With Type C, you could set the timer to run everyday between any hours
Many users use this to promote Next Day Shipping. For exmaple, order before 4PM today, order will be shipped tomorrow.
Here are the steps
Step 1: Under "Start Time and End Time:", define the start and end time, so the bar is valid to display during this period
Step 2: Under "Countdown Timer Type:", select Type C
Step 3: Under "Daily from:", define the hour of the day when the timer starts counting down everyday
Step 4: Under "To:", define the hour of the day when the timer stops counting everyday
Step 5: "Visitor Will Only See One Recurring Cycle" is unchecked by default. If this option is checked, the same visitors will only see the countdown timer for one day
For the example in the screenshot, the bar is valid to display from 12AM Oct 20th, 2016 to 12AM Oct 23th, 2016. The bar actually displays everday from 8:00AM to 4:00PM, counts down 8 hours (8 Hours between 8AM to 4PM).
It starts again in the next day with the same pattern until Oct 23th, 2016. The bar does not display for the rest of the time.
