Local <time> elements
npm install @marcoroth/local-time> This is a modern fork of Basecamp's local-time npm package and gem. The original repo can be found here: https://github.com/basecamp/local_time
Local Time makes it easy to display times and dates to users in their local time. Its Rails helpers render elements in UTC (making them cache friendly), and its JavaScript component immediately converts those elements from UTC to the browser's local time.
1. Add gem 'local_time', github: 'marcoroth/local-time' to your Gemfile.
2. Import LocalTime from @marcoroth/local-time in your application's JavaScript bundle.
``js
import LocalTime from "@marcoroth/local-time"
LocalTime.start()
`
`ruby`
> comment.created_at
"Wed, 27 Nov 2013 18:43:22 EST -0500"
`erb`
<%= local_time(comment.created_at) %>
Renders:
`html`
data-local="time"
datetime="2013-11-27T23:43:22Z">November 27, 2013 11:43pm
And is converted client-side to:
`html`
data-local="time"
datetime="2013-11-27T23:43:22Z"
title="November 27, 2013 6:43pm EDT"
data-localized="true">November 27, 2013 6:43pm
(Line breaks added for readability)
`erb`
<%= local_time(time) %>
Format with a strftime string (default format shown here)
`erb`
<%= local_time(time, '%B %e, %Y %l:%M%P') %>
Alias for local_time with a month-formatted default
`erb`
<%= local_date(time, '%B %e, %Y') %>
To set attributes on the time tag, pass a hash as the second argument with a :format key and your attributes.
`erb`
<%= local_time(time, format: '%B %e, %Y %l:%M%P', class: 'my-time') %>
To use a strftime format already defined in your app, pass a symbol as the format.
`erb`
<%= local_time(date, :long) %>
I18n.t("time.formats.#{format}"), I18n.t("date.formats.#{format}"), Time::DATE_FORMATS[format], and Date::DATE_FORMATS[format] will be scanned (in that order) for your format.
Note: The included strftime JavaScript implementation is not 100% complete. It supports the following directives: %a %A %b %B %c %d %e %H %I %l %m %M %p %P %S %w %y %Y %Z
`erb`
<%= local_time_ago(time) %>
Displays the relative amount of time passed. With age, the descriptions transition from {quantity of seconds, minutes, or hours} to {date + time} to {date}. The
Examples (in quotes):
* Recent: "a second ago", "32 seconds ago", "an hour ago", "14 hours ago"
* Yesterday: "yesterday at 5:22pm"
* This week: "Tuesday at 12:48am"
* This year: "on Nov 17"
* Last year: "on Jan 31, 2012"
Preset time and date formats that vary with age. The available types are date, time-ago, time-or-date, and weekday. Like the local_time helper, :type can be passed a string or in an options hash.
`erb`
<%= local_relative_time(time, 'weekday') %>
<%= local_relative_time(time, type: 'time-or-date') %>
Available :type options
* date Includes the year unless it's current. "Apr 11" or "Apr 11, 2013"time-ago
* See above. local_time_ago calls local_relative_time with this :type option.time-or-date
* Displays the time if it occurs today or the date if not. "3:26pm" or "Apr 11"weekday
* Displays "Today", "Yesterday", or the weekday (e.g. Wednesday) if the time is within a week of today.weekday-or-date
* Displays the weekday if it occurs within a week or the date if not. "Yesterday" or "Apr 11"
Internationalization (I18n)
Local Time includes a set of default en translations which can be updated directly. Or, you can provide an entirely new set in a different locale:
`js
LocalTime.config.i18n["es"] = {
date: {
dayNames: [ … ],
monthNames: [ … ],
…
},
time: {
…
},
datetime: {
…
}
}
LocalTime.config.locale = "es"
