daylight saving / time zone issues with as.POSIXlt/as.POSIXct (PR#10392)
Running under Windows XP 64 bit, as.POSIXlt()/as.POSIXct() seem
to think that US time zones (EST5EDT, MST7MDT) switched from daylight
savings back to standard time on Oct 28, 2007, whereas the switch
is actually on Sun Nov 04, 2007.
Examples:
> Sys.timezone()
[1] "Mountain Daylight Time"
> as.POSIXct("2007-10-30 12:38:47")
[1] "2007-10-30 12:38:47 Mountain Daylight Time&q...

3.8p1 not honoring TZ environment variable
Hello,
I just built openssh 3.8p1 on an HP-UX 11i machine. All looks well
except for the timezone. I'm noticing now that when it logs stuff to
syslog, it's off by 2 hours for me. What I've figured is this:
My timezone is MST7MDT (mountain time).
The timezone in /etc/default/tz is EST5EDT (eastern time).
There's a 2 hour difference between mountain & eastern time.
What I'm thinking is the real problem, is that it is not looking at the
TZ environment variable to get its own setting for the timezone when it

timezone conversion difficulties with the new US daylight saving time switch over

[1] "Mountain Daylight Time"

If I explicitly set env var TZ, the conversion problems go away,
but the time reported by Sys.time() is inappropriately not in daylight
saving time:

[1] "2007-10-30 13:14:38 Mountain Daylight Time"
> Sys.setenv(TZ="MST7MDT")

[1] "2007-10-30 12:14:51 MST"

If I set my system timezone to Eastern Daylight Time, and
restart R, I also get problematic behavior (as.POSIXlt
inappropriately adjusting a time by an hour on the day
after Daylight saving time ends):
