similar to: datetime_select with timezones

This is a follow-up to the thread ending with: http://rubyforge.org/pipermail/vpim-talk/2008/000120.html I too am in search of some ruby parser for icalendar which properly handles timezones on the datetimes in the icalendar RFC. As I understand it there are actually three types of times. 1) UTC times with a string form of yyyymmddThhmmssZ note the trailing Z indicates zulu time aka utc. 2)

I want to specify a different default time to datetime_select tag how can i do that. also i was looking at rails helper code ----------------------------------------------------------------------- module ActionView module Helpers module DateHelper def to_datetime_select_tag(options = {}) defaults = { :discard_type => true } options = defaults.merge(options)

Hello It seems that datetime_select, is creating an instance of the Time class. Why would that be? I found this while building a site where people can create vigils (prayer vigils, peace vigils, etc). When I added a validation method that compared start_date to created_at, it generated the error: ArgumentError (comparison of Time with DateTime failed): I was able to put a breakpoint in the

Is there a way to make datetime_select() dropdowns work on a 12hr clock? I need to make a input field that works exactly like the reminders datetime selecton dropdowns in Backpack to populate a datetime field in my DB. i.e in the format: month, day, year ? hour (1-12) minute am/pm. Should I change my database to have a separate column for date and one for time and use date_select()? Can

Hi, I have a datetime select in my form like this: DATE/TIME REPORTED: <%= datetime_select ''report'', ''rep_date'' %> This works beautifully for creating a new record. The data is saved as: 2006-08-07 11:33:00 Now, the problem is when I try to load the form with saved values to do an update. The above code works and loads the saved data in another one

I'm having difficulties with daylight saving times in US time zones. (Apologies for the long post, but the problem seems subtle and complex, unless I'm doing something completely wrong, in which case it should be evident from the first 10 lines below.) This is what I see, using a (slightly modified) example from ?as.POSIXlt : > as.POSIXlt((d <- Sys.time()), "EST5EDT") #

Friends, So there I was, minding my own business, trying to make my rails app timezone aware (DST, as well), since it''s all about the timing with this one. There are a number of excellent articles that I''ve been working off of, in particular this one internet archived version of Scott Barron''s very useful article on the subject that is no longer available at the

-------------------------- Question 1 -------------------------- I am dealing with a database that holds products and it has a datetime field called "active_at". so I have the following for active_at: <%= f.datetime_select :active_at %> It gives me 5 different params: params[:product][:active_at(1i)] params[:product][:active_at(2i)] params[:product][:active_at(3i)]

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

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

Currently using t.datetime, dates get stored with a timezone and a non- zero time. This is bad. A date restricted to the Unix epoch is unacceptable. The date range must be at least back to 1800. Need a recommendation on what SQL column type, Rails column type and Ruby object type would be the best choice, and how to avoid timezones.

Hi I have 2 question for you guys, 1. Which is the difference between this two methods? (select_datetime, datetime_select) 2.

Hi, Im trying to build a form using: <% facebook_form_for(:task, at task,:url => create_task_path) do |f| %> Assign Task To: <%= fb_friend_selector %> <%=f.text_field :ttype, :label=> "Title"%> <%=f.datetime_select :duedate, :label=> "Due Date"%> <%=f.buttons "Add" %> <% end %> But im getting an

If I have a form similar to the one below, and ''start'' is a "string" field in my Database. Is there a way to take all of the date/time params and put them into ''start'' without too much hacking? I would like this to be as clean as possible. <p><label for="start_time">Start Time</label><br/> <%=

HI, I am creating n onlinecalendar sort of functionality for which the user input for events is taken. To make it user friendly, its left to the user to write the time down rather than selecting it from a datetime field in a form . The user can also specify a timezone. And while doing so its obvious that most inputs will be an abbreviation. My question is - is there a way to convert

How do I get a value from datetime_select? Do I need to get each value from it''s dropdown element individually or is there a way to get the date by referencing one object? Anyone have any good examples? -Andy

Dear R-devels, timedatectl binary used by Sys.timezone does not always work reliably. If it doesn't the warning is raised, unnecessarily because later on Sys.timezone gets timezone successfully from /etc/timezone. This obviously might not be true for different linux OSes, but it solves the issue for simple dockerized Ubuntu 16.04. Current behavior R Under development (unstable) (2018-05-04

Last week I started to sketch out what would be involved in building a calendar app in Rails. In the process I went looking for what Ruby has in the way of Date/Time libraries, and in particular TimeZone support. Was (pleasantly?) surprised to find that Rails seems to have Ruby''s best timezone support. But it looks like it has a very serious bug, it isn''t daylight saving

Hi All In my project I am to take date of birth from user so I used datetime_select. It renders three selection boxes, year, month and day. But I want order as day, month and year. I added :order option for datetime_select, it renders normal selection boxes with order year, month and day. Why :order does not work with datetime_select? see my following code <%= datetime_select(:user2,

When I do the date +%Z I get the timezone. Which currently is EDT. I am sending information to another system, that says EDT is not a valid timezone. I have no way to modify the other system. My question is - is there a way to get the non-day-lite savings time zone ? For example EST is valid - EDT is not. Just curious if there is an easy way already present to get a standard time zone. Thanks,
