How do I set the next update time?

There are two ways to set the next update time. You can only use one of the options to set the next update time.  

Set the number of days / hours until the next update

1. Enter days, hours or minutes in the Next Update in tab
2. The grey box will automatically calculate the day and time

Choose the date and time until the next update

1. Select the 'Next Update at' tab
2. Click on the calendar icon 
3. Choose the date and time that you want the notification to expire 

If you set the next update time using the Next Update in (first tab) and then use the Next Update at (second tab) to choose a date and time then the first tab will be cleared (and visa versa).
