Shigeru,

I will try to reproduce this issue and let you know what I find.

Hi Kevin,

I have a question about the public demo server.

- publishInterval = 1000 (msec)
- samplingInterval = 500 (msec)

The following [2,Dynamic/RandomInt64] was obtained under the above conditions.

In one notification, 4 pieces of data could be acquired. The order of this JSON format

data is the dataValues list organized for each NodeId.

onDataChangeNotification(UaSubscription subscription,
                                      List<UaMonitoredItem> monitoredItems,
                                      List<DataValue> dataValues,
                                      DateTime publishTime)

t this time, looking at sourceTime, it seems that the order of time is repeated.

      "sourceTime" : "2019-08-07 11:38:08.155",
      "sourceTime" : "2019-08-07 11:38:08.655",
      "sourceTime" : "2019-08-07 11:38:08.155",
      "sourceTime" : "2019-08-07 11:38:08.655",

Is there any problem with the publishing facility of the server?
The time accuracy is msec. It is not 100nsec.
