How did you set the TZ system variable?
If you did not use Sys.putenv(), try using it instead.
Otherwise, I think you have to ask the package maintainer.
You may be misleading yourself by using Sys.time() to test whether TZ is set.
What does Sys.getenv() tell you?
I get a timezone code from Sys.time() even when TZ is not defined
(see example below).
(but I do have a different OS)
> Sys.timezone()
[1] ""> Sys.time()
[1] "2005-07-06 07:34:15 PDT"> Sys.getenv('TZ')
TZ

> Sys.timezone()
[1] "US/Pacific"> Sys.getenv('TZ')
TZ
"US/Pacific"> Sys.time()
