epicsTS is the one passed to kafka: https://gitlab.esss.lu.se/epics-modules/ADPluginKafka/-/blob/2.0.2/adpluginkafkaApp/src/KafkaPlugin.cpp?ref_type=tags#L40 The documentation is a bit confusing on what is the difference between epicsTS and timeStamp, but apparently both can be modified with no problems. After [this discussion](github.com/areaDetector/ADCore/issues?q=is%3Aissue%20state%3Aclosed) I decided it was fine to keep the epicsTS in nanoseconds with the EVR values.
