How to get time differences in consistent units?
I'm still having trouble getting to grips with time classes.
I wish to calculate the difference in days between events.
Browse[1]> insp.j$First
[1] "2002-02-19 13:00:00 NZDT"
Browse[1]> spray.j$Date
[1] "2001-11-29 13:00:00 NZDT"
Browse[1]> insp.jk - spray.j$Date
Time difference of 82 days
If I save insp.jk to a vector, I get a nice useful value of 82.

time zones, daylight saving etc.
Hi, I have a whole bunch of data, which looks like:
15/03/2003 10:20 1

15/03/2003 12:02 0

etc. (times given on a 24 hour clock)
and goes on for years. I have some code:

as.POSIXct Bug when used with POSIXlt arg and tz= arg (PR#3646)
Tracking down this bug was joint work with Jermoe Asselin (jerome at
hivnet.ubc.ca) and Patrick Connolly (p.connolly at hortresearch.co.nz). We
collectively were able to determine that this is a problem in both Windows 2000
and in Linux and by testing it in our three time zones that it seems to be
daylight savings time related.
Conversion of POSIXlt datetimes to POSIXct appears to have problems.

tzdata - extra info.
Sorry for the extra info required, but I had digest mode turned on and
wouldn't have received the mailing till tomorrow.
I have since updated the data manually, but after 'yum update tzdata' was
run, the zdump -v for EST5EDT and America/New_York all still showed a date
of April 1, instead of March 11. After manually fixing, it is correct.
This was mostly a question about why yum

This has to do with your own timezone. If I run that code on my computer,
both formats are correct. If I do this after
Sys.setenv(TZ = "UTC")
Then:

Windows 2000 Bug in GMT +/- n Timezones (PR#3644)
Tracking down this bug was joint work with Jermoe Asselin (jerome at
hivnet.ubc.ca) and Patrick Connolly (p.connolly at hortresearch.co.nz). We
collectively were able to determine that this is a problem in Windows 2000
but not in Linux.
Timezones of the form GMT-5, GMT+3, etc. do not work properly in Windows 2000
for nearby dates in daylight savings time although they do work for nearby
dates

tzdata
I read a few days back on the list where the tzdata rpm was to take care of
the new DST rules. I run CentOS 3 servers, and did a 'yum update tzdata' ,
but received a 2006a update of the rpm.
Is this proper? It sure didn't fix anything.
Thanks

Weird POSIXct behaviour
Friends
I have an xts that I wish to access.
Browse[2]> DATA.ba[[p]]["2012-03-20 00:59:57","bid"]
bid
2012-03-20 00:59:57 1.4993
So far so good.
Now putting the index into a variable:
Browse[2]> Time
[1] "2012-03-20 00:59:57 NZDT"
Browse[2]> DATA.ba[[p]][Time, "bid"]
bid
Where has it gone?

Understanding POSIXct creation on different OSes.
Hello,
Following Dirk's post here: https://github.com/Rdatatable/data.table/issues/1619
we would like to clarify if this is the right behaviour, and if so,
the rationale behind it.
Here's the summary (thanks to Dirk and Joshua):
Sys.setenv("TZ"="America/Chicago")
dates = as.Date("2016-03-02") + (0:3)*7 # four Wednesdays
# [1] "2016-03-02"

The RPC server is unavailable on Samba 4 clients
Hi,
I used to upgrade/migrated samba 3.3.10 to samba 3.4.17 with LDAP backend
in place, while upgrading the CentOS from 5.5 to 5.9. In place to retain
the trust relationship.
The users can able to login without re-authentication from existing
machines. Tested 3 XPs, and 3 Win7 but it takes 5-8 mins to login compared
to 1 win7 that was re-connected (disconnected from domain, restart, then

Trouble resolving some group membership after upgrade from 4.8 to 4.10
Hello,
I had been running Samba 4.8 for a few years without any problems, and then upgraded to 4.10. Since then I?ve been having problems with some accounts connecting, while some connect fine still. I haven?t been able to figure out why. My server is a relatively simple standalone server, using the LDAP password backend.
A failing user authenticates OK and ends up like this in the logs:

smbfs timestamp problem
Here's a curly one.
I have a share mounted via smbfs on my linux desktop. This share is on
a NetApp filer somewhere, but I've also tried this on a an old linux
server as well, and I have the same problem.
Basically, since day light savings came into effect here (NZDT or
+13), any file I create on the share gets a time creation timestamp
that is way out (approximately 12 hours and 48

Converting a dataframe column from string to datetime
Hi,
I have a dataframe column of the form
v<-c("Fri Feb 05 20:00:01.43000 2010","Fri Feb 05 20:00:02.274000 2010","Fri Feb 05 20:00:02.274000 2010","Fri Feb 05 20:00:06.34000 2010")
I need to convert this to datetime form. I did the following..
lapply(v,function(x){strptime(x, "%a %b %d %H:%M:%OS %Y")})
This gives me a list that looks like
