How to disable warning R: object time zone (UTC) is different from the current time zone ()

Question

I keep getting this warning: timezone of object (UTC) is different than current timezone (). My current time zone is "EET", as shown by Sys.timezone() .

Is there a way to change the R timezone to UTC, instead of taking it from my system? Or disable the warning?

Answer 1

Try the following:

 Sys.setenv(TZ = "UTC") 

Answer 2

If you can get a local time zone, this is from:

  Sys.timezone() [1] "" # So in my case nothing there 

And no Sys.timezone () <- function

  Sys.time() [1] "2011-01-06 16:01:10 EST" 

But, obviously, there must be something. And here's how to convert to another time zone:

  strftime(Sys.time() , tz="UTC") [1] "2011-01-06 21:02:48" 

For further specific advice, it is possible that if you proposed dput () results for an object, we all will have access to any necessary attributes to answer other questions.

Answer 3

If you are sure that your code works and other sources of warnings are unlikely, just put a call inside suppressWarnings ().

For instance,

 require(quantmod) getSymbols("FDX") suppressWarnings(chartSeries(FDX,theme="white"))
