This data structure of the CAA_RealTimeClock.library defines a time.
Two formats are supported:
- Absolute format: defines an exact time. “uiYear”, “uiMonth”, “uiDay”, “uiHour”, “uiMinute” and “uiSecond” define the exact time. "uiWeekday” is of no importance.
- Day of the month format: is selected by setting ”uiYear” to 0. „uiWeekday“ defines a weekday and “uiDay” specifies the day of the month in a value range of 1..5. This notation makes it possible to define the first Sunday in April as well as the last Thursday in October (“uiDay” = 1 corresponds to the first weekday in a month, “uiDay” = 5 corresponds to the last weekday in a month)
