JavaScript Library To Display Current Local Times Around The World – jsclock

jsclock is a standalone JavaScript library for creating a world clock to display current local times around the world based the timezone.

How to use it:

Load the clock.js into your html page.

<script src="clock.js"></script>

Create the html for the world clock.

<div class="myclock">
  <div>In Paris, it is</div>
  <div id="CET"></div>
</div>
<div class="myclock">
  <div>while in Los Angeles it is</div>
  <div id="America/Los_Angeles"></div>
</div>
<div class="myclock">
  <div>Did you know that Caracas is in UTC-4:30?</div>
  <div id="America/Caracas"></div>
</div>

Initialize the clock.

JsClock.showTime('CET');
JsClock.showTime('America/Los_Angeles');
JsClock.showTime('America/Caracas');

As clock is embedded into user-defined container element, its general style can be customized as needed.

.myclock {
  font-size: 18pt;
  background-color: #f0fff0;
  text-align: center;
  width: 20%;
  height: 10%;
  margin-left: auto;
  margin-right: auto;
  margin-top: 20px;
}
/* date-time formatting is done with dedicated css styles: */
.jsclock-date-sep:after { content: "/"; }
.jsclock-time-sep:after { content: ":"; }
.jsclock-datetime-sep:after { content: " "; }
/* every element can be customized with own style; some elements additionally have common style classes */
.jsclock-date-element { font-size: 14pt; }
.jsclock-hours { font-size: 26pt; }
.jsclock-minutes { font-size: 26pt; }
