[R] setting timezone variable permanently...

[Jeff Newmiller]

As I said, the tz is linked to your data, not where you OR your compute server are, so setting TZ in your R code or specifying it as the tz argument when you convert it are the best options.

If you choose to use your OS to set it that is up to you... but your code should not depend on that setting either way.

In fact the timezone you set should be linked with the data files you are using... if you work with time data from different places then you should set it appropriately for that data at the point in your script where you do the import.
