How do I set my timezone to pacific standard time?

Question

Noob question - I'm trying to set my timezone to PST but keep getting unknown timezone warnings. My macbook's timezone is set but isn't communicating with R and R doesn't seem to like my request for PST. I'm sure this is an easy fix but can't seem to find any solutions that have worked yet. Thanks in advance!

Answer 1

There is a potential answer on the R-bloggers website here .

It combines the above comment: Sys.setenv(TZ="America/Los_Angeles") with some background info on the problem.

Also, see this question on StackOverflow here .

The answer basically states that anything less than version R 3.4.3 will not get along with MacOS 10.13 'High Sierra' for timezones.

So check with...

 R.version[names(R.version) == "version.string"] #OR
 sessionInfo()$R.version$version.string #and if it's less than 3.4.3,

download the latest R version here: https://cran.cnr.berkeley.edu/

This should fix it.
