There is incompatibility between R strptime and musl libc. I posted about it on their mailing list, but they need more information I can't provide, so I'm forwarding the message here in hope R developers can help. Thanks. ---------- Forwarded message ---------- From: Rich Felker <dalias at libc.org> Date: Thu, Feb 4, 2016 at 2:07 PM Subject: Re: [musl] strptime() question To: Alba

It is setting TZ and using tzset(). R is not multi-threaded so it is safe. Simon figure out the important settings from the config.log and config.h files on a musl system: /* #undef USE_INTERNAL_MKTIME */ #define HAVE_TM_GMTOFF 1 #define HAVE_TM_ZONE 1 Does this help anyone debug the issue? Simon just went on vacation. On Th...

Hi, A question regarding chroot, internal-sftp, and time zones: Is it possible to get the time stamps presented by the chrooted internal-sftp to always be aligned with the system global time zone setting? What is the reason this not done by default, that is couldn't the chrooted internal-sftp inherit the time zone information from the SSH daemon? /John -- John Olsson Ericsson AB

...ion purposes. They may be populated when constructing the time object, but not used for later calculations. Instead, the standard mktime() always uses the process-global timezone, so when R processes POSIXlt values, it has to set the TZ environment variable from the 'tzone' attribute, call tzset() to set global state in the library, use mktime() to obtain seconds since epoch, and then reset everything back. > As I mentioned, fortunately, I only have local time and GMT and it > would be fine to convert them to a single time zone if that is what > it takes to work with them in R....

...bly. difftime: difference between times in secs. (The wrappers for the last two could handle POSIXtime and POSIXtm objects.) (Perhaps if these do not exist on a platform (unlikely) we can have less accurate alternatives in our code. They exist on Windows.) Possibly we might want to allow tzset: set a time zone, for the above functions or perhaps better just have tz as an argument to the conversion functions. Is this is a sensible design strategy? I am reluctant to add another set of date functions after packages date and chron, but cannot see how to easily leverage those to d...

Can anybody give me a hint why as.POSIXlt doesn't recognize the same timezones that zdump knows about (Linux Suse 8.1 and Suse 7.3)? Is there a workaround?

I am analysing some data collected over a number of months from Allentown, PA, which is just north of Philadelphia. I am using as.POSIXct for dates and times, and I need to get the timezone specification correct. Going on the documentation for DateTimeClasses, I believe one way to specify the correct time zone is tz="EST5EDT" I would be grateful for any advice on this. I ask

...at man strptime on my system says about this, but maybe it suggests that timezone information might be used if provided... %Z Timezone name or no characters if no time zone infor- mation exists.

Hi, I have just tagged 3.7.1-rc1, so it is ready for testing. As a reminder, when doing regression testing, use the 3.7.0 release as your baseline. Thanks, Tom
