How to use telegraf timestamps with the telegraf gnmi input plugin instead of using the devices timestamps

how_to_use_telegraf_timestamps.md

With the telegraf gnmi input plugin, in order to use the telegraf timestamps instead of using the devices timestamps:

Here's the fork https://github.com/rski/telegraf that was used for:
influxdata/telegraf#8411
influxdata/telegraf#8420

Until this option will become natively part of Telegraf (influxdata/telegraf#8689), you can build a docker image from this fork:

git clone https://github.com/rski/telegraf
cd telegraf
make docker-image

Or you can build a docker image from this Dockerfile

FROM golang:1.15.6-buster
WORKDIR /go/src
RUN git clone https://github.com/rski/telegraf.git
RUN cd /go/src/telegraf && make
RUN cp /go/src/telegraf/telegraf ../../bin/.

Then, add use_local_timestamp = true in the [[inputs.gnmi]] configuration.

There is new update from Telegraf regarding the issue influxdata/telegraf#8411
The solution for this will be to utilize the Starlark processor
There is this example script that can be added to use the current/local timestamp over the field device's timestamp.
