How to encode a DateTime object

[Jeremy Begg]

Hi,

One of the properties we need to publish is a BACNET_DATE_TIME value.
There seems to be some support for it in src/datetime.c but I don't see routines for encoding or decoding these.

Using the example BACnet server (in the demo directory) would it be as simple as ...

int DateTime_Value_Read_Property(BACNET_READ_PROPERTY_DATA * rpdata) {
...
    BACNET_DATE_TIME bdatetime;
    switch (rpdata->object_property) {
...
        case PROP_PRESENT_VALUE:
            // get the local date & time as a BACNET_DATE_TIME value
            get_datetime(&bdatetime);
            // encode it as a date followed by a time
            apdu_len = encode_application_date(&apdu[0], &bdatetime.date);
            apdu_len += encode_application_time(&apdu[apdu_len], &bdatetime.time);
            break;

Thanks,
Jeremy Begg

Yes, it is as simple as that. There is already a helper in src/datetime.c file:

bacapp_encode_datetime()
