BACnetDateTimePatternValue.PresentValue (PROP)¶

PROPERTY PresentValue : CmpBACnet.IEC_BACNET_DATE_TIME

Please note the difference to BACnetDateTimeValue.PresentValue - it can be fully specified or fully unspecified. BACnetDateTimePatternValue.PresentValue does represent a date time pattern which might be partially unspecified, so we’re going to use CmpBACnet.IEC_BACNET_DATE_TIME which provides this flexibility but is a bit more eqloquent to use. Use CONSTANTS.YEAR_UNSPECIFIED .DAY_OF_MONTH_UNSPECIFIED .HOUR_UNSPECIFIED .MINUTE_UNSPECIFIED etc. to set the pattern.
