JKL Timezone Converter

ཞིབ་བརྗོད།

I live in South Korea. But I have loads of friends in the US and elsewhere in the
world. Additionally, sometimes I need to arrange Skype calls or meetings with
someone in a different timezone, OR there is an online event that I really want to
attend – in a different timezone.

I needed a way to quickly and easily convert from one date and time in a particular
timezone to another. (I hate Googling it every time, or looking up timezone tables
and doing mental math.) What I really wanted was something I could just point,
click, submit and have it spit out the relevant time for me in my timezone. So,
I created this plugin which does just that.

Requires WordPress 3.5 and PHP 5.4 or later.

Special Features

  • Automatically defaults to your current date, time, and timezone
    based on your WordPress General Settings
  • Allows you to select a City or Manual UTC offset for conversion in the same way
    the WordPress General Settings Page does
  • Uses a special jQuery calendar popup for easy date selection
  • Only allows one instance of the Converter to run on a Page at one time

Notes

  • Multiple widgets are allowed at once (on the same Post/Page)
  • Multiple shortcodes (on the same Post/Page) are disabled – multiple shortcodes
    will display only ONE form
  • On Posts/Pages with a shortcode, the widget will be disabled

Planned Upcoming Features

  • AJAX form submission to prevent page reload
  • Ability to give the shortcode a specific date and time (like for an Event you’re
    promoting) that will set as the default for the Converter on that particular Page
  • Ability to change the color of the form (shortcode) or converted result (widget)
  • Possibly allow users to select whether or not to display multiple forms in shortcodes
    and/or widgets

Translations

  • English (EN) – default
  • Korean (KO) – upcoming

If you want to help translate the plugin into your language, please have a look
at the .pot file which contains all definitions and may be used with a [gettext]
editor.

If you have created your own language pack, or have an update of an existing one,
you can send your [gettext .po or .mo file] to me so that I can bundle it in the
plugin.

Tips

As a general rule, it is always best to keep your WordPress installation and all
Themes and Plugins fully updated in order to avoid problems with this or any other
Themees or Plugins. I regularly update my site and test my Plugins and Themes with
the latest version of WordPress.

How can I change the style of the plugin to match my website?

Each element within the jkl_timezones_form contains its own unique CSS identifier,
allowing you to hook into those in your own Custom CSS stylesheet.

To easily find out which classes control which elements, simply open your site in
a modern browser (Google Chrome, Firefox, Opera, or Internet Explorer 9 or later)
and right-click on the element you wish to style. Then find Inspect in the pop-up
contextual menu.

Why does the Timezone Converter always show UTC time and not my current timezone?

In order for your current timezone to show up in the timezone calculator as the
default, you first need to SET your default timezone in the WordPress Settings Page.
In the WordPress admin menu, go to Settings -> General and find the dropdown to
set your timezone.

Note: If you select a manual UTC time (like +9:00), then the plugin will GUESS
which city you are located in based on that timezone (and it might not be entirely
accurate). For example, I am based in Seoul (UTC +9:00), but when I set it to UTC
+9:00
rather than the city name Seoul, the plugin guesses that my city is actually
Tokyo (which is located in the same timezone).

Why doesn’t the Sidebar Widget also show up on a Page using the shortcode?

Simple: it’s best to not allow TWO separate instances of the Timezone Converter
to run on the same page. It’s overkill. You only need one per page. The same is
true for multiple shortcodes on one page. Only ONE instance of the Timezone Converter
should be used on any one Page.

Why does my Page reload every time I click the Timezone Converter buttons?

There is currently no AJAX functionality implemented by this plugin to maintain
the state of the Page and dynamically calculate and show the answer without a
reload. This is a planned feature for an upcoming release.

Why do I have to scroll down the Page to see my results after conversion?

Currently, the plugin doesn’t remember your page position when you submit the
conversion form, so because the form completely reloads the page, it thinks this
is the first time you’re loading, so it will load to the top of the page.

Remembering page position is a planned upcoming feature, but it will be
unnecessary if/when I implement dynamic calculations with AJAX.

Why do some of the Timezone Converter fields appear out of place?

For the most part, it depends on how your Theme styles those elements. I did my
best to style the form very simply and plainly, but some elements may appear out
of place in your installation due to your Theme’s default styles. In order to fix
this, add some Custom CSS (preferrably using Jetpack’s Custom CSS feature, or
another that doesn’t require modifying the Theme or Plugin files).

See the first question above for more info on how to do create Custom CSS for the plugin.

Can you ADD / REMOVE / CHANGE features of the plugin?

Sure, I’m always open to suggestions. Let me know what you’re looking for. Feel
free to open a GitHub Issue on the plugin repository
to let me know the specific features or problems you’re having.
