You must provide the timestamps in UTC timezone. Current time is available with PsUtils.UTCNow.

Sorry I didn’t understand how it can be used in these program code
name:=TPsString.Create(nil);
name.Value:= Info.softSettings.linkSettings.name ;
idx:= OPCserver.AddressSpace.AddVariable(ctrlIdx, name, ‘Name’);
and
var
arr: TPsFloatArray ;
HistoryData : array[0..POINT_COUNT-1] of double;
…
HistoryData:= ….
arr.AssignArray(HistoryData) ;

Current time is 14:59
stro:=TPsString.Create(nil);
stro.SetPropValueAt(vpValue, ‘tst’, vpqGood, UTCNow ) ;
in browser time is 17:59 ???
stro:=TPsString.Create(nil);
stro.SetPropValueAt(vpValue, ‘tst’, vpqGood, Now ) ;
in browser timestamp is 20:59 ???
and UTC now is 11:59 .

correct time is
arr.SetPropValueAt(vpValue, mas, vpqGood, UTCNow – Abs(Now-UTCNow ));

Which client application are you using? What is the TimeBias used?

In your Prosys OPC Test Server also time for 3 hours ahead of local time.

And what does our Prosys OPC Client show? The TimeBias parameter is the problematic one, which is not always interpreted or used correctly. If you check the LocalTimeBias option in Prosys OPC Client, the server will convert to the local time. This will make the client use NULL for the parameter. If the server is not supposed to convert, the client should use 0 for the TimeBias.
It feels like the client is requesting local time, but still converting the timestamps itself, too.
