For the time interval, you can use the 'D HH:MM:SS' format where D represents days with a range from 0 to 34. A more flexible syntax is 'HH:MM', 'D HH:MM', 'D HH', or 'SS'.
If you use the delimiter:, you can use 1 digit to represent hours, minutes, or seconds. For example, 9:5:0 can be used instead of '09:05:00'.
