How specify a timezone for all my R session ?

Hello,

I use rstudio workbench to launch R sessions and I would like to have the Europe/Paris timezone directly configured because it would avoid launching this line of code at each session:
Sys.setenv(TZ='Europe/Paris')

to run the rstudio service I use a GCP VM and when the session starts kubernetes will create a container.

So I have a workbench.sh file for the VM configuration and a Dockerfile to create the containers

Can you help me please ?
