similar to: Ruby Dates - help

Hello, This is likely fairly silly question, and I apologize to whomever takes the time to respond. I am a relatively new user of R, on Windows XP, version 2.3.1. Say I have a data table that looks like the following: x Date Location Amount Blue Green 1 01/01/2001 Central 1817 TRUE FALSE 2 01/02/2001 Central 20358 FALSE TRUE 3 05/08/2001 Central 16245 FALSE TRUE 4

Hi, I tried to read xlsx files by "XLConnect" packages, but the dates are one day earlier than it is supposed to be. I moved from California to Taiwan (Eastern Asia), and it worked well in California, but not in Taiwan. Even if I adjust my Mac time to California time zone, it gives the wrong dates. I don't know which part of the setting (in RStudio or in my Mac?) I should adjust.

Hello all, I am currently evaluating the vpim libraries and like them very much. However there''s one thing I can''t get done: How can I set the TZID parameter for DTSTART/END dates so my encoded ICS file looks something like this: BEGIN:VEVENT ... DTSTART;TZID=Eastern Time:20071201T080000 DTEND;TZID=Eastern Time:20071207T110000 ... END:VEVENT I managed

Jim, I don't see how that link could be related to John's issue. Symptoms related to your link involve discrepancies of four years whereas John is seeing discrepancies of one day. John, I do not see any attached files. Regards On Sat, Sep 23, 2017 at 1:30 PM, Jim Lemon <drjimlemon at gmail.com> wrote: > Hi John, > It could be due to this: > >

I don't use SPSS but following through on your detective work can provide the likely answer. First note that both date numbers are evenly divisible by the number of seconds in a day, i.e. 24*60*60. This suggests that these numbers are seconds since some origin. Since we know "2003/02/11" corresponds to 13264300800 we deduce that the origin must be spss.orig <-

The return value of Sys.time() today with a timezone of US/Eastern is unchanged between 4.0.3-patched and devel, but on devel the following test fails all.equal(x, as.POSIXlt(x)) with x = Sys.time() This means that devel does not complete make tests (failure on tests/reg-tests-2.R) It is entirely possible that it is an error on my end, I use export TZ="US/Eastern" but I have been

Dear R users, I am struggling a bit with the converting dates to full POSIX timestamps, in particular, I would like to somehow force the timezone to be local, i.e. the output of as.POSIXct(as.Date("2008-07-01")) should always be equal to "2008-07-01 00:00:00", is that achievable ? I tried to set the origin and the timezone, neither of which seems to make a difference. On my Mac

Yes, the potential issue I see is that make check fails when I explicitly set TZ. However, I set it to be the same as what the system reports when I login. Details: The system (RHEL) I am working on has $ strings /etc/localtime | tail -n 1 EST5EDT,M3.2.0,M11.1.0 $ date +%Z EDT $ echo $TZ US/Eastern On Fri, Oct 2, 2020 at 9:48 AM Sebastian Meyer <seb.meyer at fau.de> wrote: > Thank

Hi John, I was able to reproduce your problem in my environment. I modified the statement date11<-as.Date(a_col$date, format="%Y-%m-%d") to date11<-as.Date(as.POSIXlt(a_col$date),format="%Y-%m-%d") which then gives the output you would like to see (at least on my system) > date11 [1] "2004-01-01" "2004-01-02" "2004-01-05"

I have a couple questions... I am in Indiana and our time zone is changing. I used to choose America/Indiana/Indianapolis as the zone and we are changing to Eastern. Question 1) Is there a command line only way to change my timezone? I dont have access to X to run system-config-time. Doing a "system-config-time --help" or "system-config-time -h" did not give any information.

Hi, Thank you for all your responses. For Eric, The files are attached. (I believe it was also attached in my first message) For David, Could you send me the link regarding possible solutions or a more comprehensive description of the problem?

I have some questions and comments on timezones. Problem 1. # get current time in current time zone > (now <- Sys.time()) [1] "2003-07-29 18:23:58 Eastern Daylight Time" # convert this to GMT > (now.gmt <- as.POSIXlt(now,tz="GMT")) [1] "2003-07-29 22:23:58 GMT" # take difference > now-now.gmt Time difference of -5 hours Note that the difference

Which is why I always symlink /etc/localtime Not only does it solve these issues, but it makes it very clear which timezone is selected! -----Original Message----- From: centos-bounces at centos.org [mailto:centos-bounces at centos.org] On Behalf Of Aleksandar Milivojevic Sent: Monday, November 07, 2005 2:45 PM To: centos at centos.org Subject: Re: [CentOS] New Standard/Daylight time-change

After I attempted to add ActionMailer functionality, it gave the "Application error (Rails)" and now, everything on my site works, except for the part where the Actionmailer ''would have'' sent the email. I took that out now, re-uploaded the file, and ran "killall -USR1 dispatch.fcgi" and still nothing. Everything else works, except that. Any idea what

I hope my problem is not too basic to post here. I am a beginner having problems with some matrix manipulation. The data I am working with are sites with hourly ozone readings and is in a matrix where each row is a site and each column is an hourly reading. So for 10 sites, one day's worth of data is a 10x24 matrix - column 1 is the ozone measurement for midnight GMT, column 2 is ozone at

Hi, Installed Caesar 3 this morning under wine-20041019. C3 has worked for a long time, but doesn't work under this version due to, of all things, time zone information that's missing??? caesar@flash caesar $ wine .wine/drive_c/SIERRA/Caesar3/c3.exe fixme:ntdll:TIME_GetTZAsStr Can't match system time zone name "PST" to an entry in TZ_INFO fixme:ntdll:TIME_GetTZAsStr

I am using POSIXct objects to store my date/time information. If I am plotting less that 2 days worth of data, I get the correct tick marks on the x-axis which is showing the 'day HH:MM' and these line up with the data points. If the data spans more than 2 days, the tick marks are now off. In the data below, I am creating some sample data and plotting the points. I am in the Eastern
