Condition Time set to 0 generating an Alarm from a timed callback

[giuseppedevito]

Description

I have a timed callback that read a temperature value and, if this value is over a threshold, a Condition
is set to active state setting ActiveState->Id filed to true. Before the ActiveState->Id field is set to true,
I set the "Time" of the condition using

UA_DateTime ts = UA_DateTime_now();

UA_Server_writeObjectProperty_scalar( server, conditionNodeId, UA_QUALIFIEDNAME(0, "Time"), &ts, &UA_TYPES[UA_TYPES_DATETIME] );

But in UAExpert, where the Alarm message, comment and status is showed correctly, I see
2000-01-01T00:00:00.000Z as time value.

The correct time is set instead, in the Enabled, Acked and Confirmed Callback, using the same code as above.
It seems that, after I set the time in the callback, the Time is set again to 0 when the event is generated.
