= Timepiece

Timepiece is a Rails plugin providing a simple digital clock, accurate to your server's time and maintained by jQuery.

== Installation

1. Add Timepiece to your application's Gemfile

   gem 'timepiece'

2. Require timepiece in app/assets/javascripts/application.js

   //= require timepiece

3. If you want to use the new analog clock, you also need to require timepiece in your css

   *= require 'timepiece'

or if you're using SCSS

@import 'timepiece';

Note: If you're using Turbolinks with your Rails project, you should also install jquery-turbolinks to ensure functionality is maintained between page loads.

== Usage

• Add a functional clock to your views

  <%= timepiece %>

• Pass a timezone paramater (Defaults to 'UTC')

  <%= timepiece('London') %>

• Show a 12 hour clock by specifying its type: explicitly

  <%= timepiece('London', type: '12') %>

=== 12 Hour Clock Options

By default the 12 hour clock displays time without any leading character, in the format '1:23pm'. You can add either a zero, as present on the 24 hour clock, or a leading space character the size of a numerical digit - useful for keeping your clocks aligned. To achieve this, set the Timepiece's lead:

• To add a leading zero to hour values less than ten

  <%= timepiece('London', type: '12', lead: '0') %>

  or

  <%= timepiece('London', type: '12', lead: 'zero') %>

• To add a space character

  <%= timepiece('London', type: '12', lead: '_') %>

  or

  <%= timepiece('London', type: '12', lead: 'space') %>

You can apply your own styles to any part of the Timepiece clock. For instance, you can capitalize the AM/PM abbreviation by targeting the span with class 'timepiece-abbr'. By default, the abbreviations are displayed without punctuation. To add punctuation, you can specify it with the abbr_sep: option.

• Add punctuation to am/pm abbreviation

  <%= timepiece('London', type: '12', abbr_sep: '.') %>

== Analog

New to version 0.2.0+, you can now include analog clocks in your projects.

• The helper takes the same timezone parameter as the digital version (defaults to 'UTC'):

  <%= analog('London') %>

• To specify a certain size for the clock, use the size parameter (defaults to 10em):

  <%= analog('London', :size => '100px') %>

  Note that if you pass a percentage, the size will be set as a percentage of the containing div.

== Timer

It is now also possible to make use of a basic timer. To start a count from Time.now, simply include timer in your Rails projects.

• The helper also takes a time object as a parameter, for example:

  <%= timer(User.first.created_at) %>

== Countdown

There is also a basic countdown implementation. To start a countdown to 2016, simply include countdown in your Rails projects.

• The helper also takes a time object as a parameter, for example:

  <%= countdown(Time.new(2016, 3, 14)) %> <%# My birthday and, of course, Pi day %>
