Historical timestamp trend

[Indrani125]

I am working on MQTT Client driver available in WinCC OA 3.16. I am trying to push values, status and timestamp using JSON Profiles.
Is it possible to archive values with older timestamps using MQTT Protocol?
The format is shown as under:
{"Status":0,"Time":"2019-10-11T08:50:15.658Z","Value":85}

I tested with past values but the same was not reflected in the archives.

Do you want to write historical values into the WinCC OA database?
If you want to write for a dp element a value which is older than the current timestamp of the original value you have to write a correction value using dpSetTimed() and the attribute _corr.._value.
