If your discount has an unlimited duration, you can use this section to set a duration. If your discount has a limited duration, you can use this section to edit it. Text at the top will tell you when the discount ends, if applicable.
Deselect Unlimited duration to set duration terms, or select it and press Save to remove existing duration terms. To choose or edit duration terms, press the calendar icon and select the date of your choice. You can optionally edit the time by pressing the clock icon. When you're finished, press OK. Finally, press Save on the discount edit page.
The green section on the left shows the hour, minute, and AM / PM distinction. To change from AM to PM or vice versa, press the option you'd like to switch to. The selected option is the one in bold text. To edit the hour, make sure the hour on the left is in bold. If it isn't, press it.
To proceed, either press the hand and rotate it to the hour of your choice (you can then edit the minute by clicking the minute text on the left), or you can press the hour of your choice directly (and the clock will then automatically switch to minute editing mode). Rotating the hand will only allow full number selections.
To edit the minute, make sure the minute on the left is in bold. If it isn't, press it.
You can either press the hand and rotate it to the minute of your choice, or you can press the 5-minute increment of your choice directly (and the clock will then automatically switch to hour editing mode). In order to set a minute that's not an increment of 5, you have to press and rotate the hand.
When you're finished, press OK. Finally, press Save on the discount edit page.
