Timezone issue with strftime/strptime and %z and %Z
Hello!
I've been trying to get this right for quite a while now and fear
there is an easy solution I just don't see. I did not have this
problem in Linux, and I searched r-help and Google but did not find a
solution, but of course I am grateful for and resources I might not
have found our not understood yet.
I try to parse a time stamp with time zone. I essentially just want to

Timezone conversion on Ubuntu 20.04
Hi all,
I am testing R 4.0 and ran into an issue with timezones on Ubuntu
Focal: converting a timestamp to another timezone results in NA:
as.POSIXct(as.POSIXlt(Sys.time(), tz = "CET"), tz = "EST")
This only happens on Ubuntu Focal, it seems to work fine on Ubuntu
Bionic. I am the standard ubuntu docker image icw/ r-base from Dirk's
ppa:edd/r-4.0 on both systems.

Timezone problem with 3.4.2
Colleagues
I just installed 3.4.2 on a Mac running High Sierra.

Time zones in POSIClt objects
POSIXt vectors do not support different time zones element-to-element.
If you want to keep track of timezones per element, you have to create a vector of timestamps (I would recommend POSIXct using UTC) and a parallel vector of timezone strings. How you manipulate these depends on your use cases, but from R's perspective you will have to manipulate them element-by-element.

List of all times zones in R
Hi all, in R I have?Sys.timezone() function to get the current working
Time zone. However I want to have a vector to get the list of all
available time zones, like say, LETTERS gives me all letters. Is there
any function like that?
Thanks in advance,

Time zones in POSIClt objects
Sys.setenv(TZ = "GMT") will set the local time zone to GMT so there
would only be one time
zone regardless of whether local or GMT were used.

Timezone problem with 3.4.2
From Peter Dalgaard announcement earlier today.
CHANGES IN R 3.4.3:
INSTALLATION on a UNIX-ALIKE:
* A workaround has been added for the changes in location of
time-zone files in macOS 10.13 'High Sierra' and again in
10.13.1, so the default time zone is deduced correctly from the
system setting when R is configured with --with-internal-tzcode

Thanks for pointing this out. I did a default installation of R. Does this mean that I need to reinstall from the command line?

Timezone warnings on package install in R-alpha
Dear all,
As of the current R alpha release, I'm seeing timezone-related warnings on
installing any package (including the recommended ones), which I haven't
seen before. For example,

Sweave output encoding in R-2.10.0beta on Windows (Rgui <-> Rterm)
Dear developers,
I have come across a (somewhat strange) change in the encoding of Sweave
output from R-2.9.2pat to R-2.10.0beta (apparently specific to Rgui) on
Windows installations. Of course, the NEWS file contains quite a few
changes concerning encoding, but I was not able to locate an entry which
explains the observed behaviour. I am not very familiar with
encodings/locales/codepages,

output of the balance with

after calling the previous line I press the print key on the balance which triggers sending one line
of text to the serial connection and with R 2.9.2 I get something like

Methods not loaded in R-Devel vs 2.8.1
Dear list-member,
I am currently developing a package with S4 classes. The NAMESPACE and DESCRIPTION is printed below. Within this package I have set a method "residuals" for two classes. In version 2.8.1 these two are reported whereas in R-Devel (2009-01-28 r47766). What have I missed? What has changed and how can I rectify the issue? Your help and pointers are welcome.
