This is a fairly simple plugin used to display the date and time in any widget-enabled location.
There were two goals for this plugin:
<ul>
<li>Provide a means to have the date and time produced match a specific timezone.</li>
<li>Enable complete customization over how the date and time is formatted.</li>
</ul>
I think that I’ve done a fairly good job of meeting those goals. Admittedly, setting either field is fairly user-unfriendly. The timezone specified must match <a href="http://us3.php.net/timezones" rel="nofollow ugc">PHP’s List of Supported Timezones</a>. The date and time format has the same requirements as the format parameter of <a href="http://us.php.net/date" rel="nofollow ugc">PHP’s date() function</a> (for obvious reasons since the defined format is actually passed directly to the date function in the code 🙂 ).
If this plugin gets enough attention and use, I’ll find ways of easing the use. I think a series of drop-downs would make selecting the options easier, so that would be the option used if people are interested. If you happen to be one of those interested people, please send me a message on our <a href="http://realthemes.com/contact-us/" rel="nofollow ugc">contact page</a>.

Current Date & Time Widget

WordPress displays all dates and times based on a site-level timezone setting configured in the admin back-end. The problem is when you user base handles people from all over the world date and times really don’t mean much any more.
This plugin enables the user to select their own timezone and it handles the date and time conversion in both the front-end and admin section of the site.
The plan is to start out simple and improve from there. Currently, due to some complexities with time conversions, this plugin requires your site-level timezone to be set to UTC+0, UTC or some other timezone with no UTC offset. You can find this setting in the admin section under Settings -> General.
Also, please note that if you are changing your site-level timezone, this will not update any data in the database. WordPress simply assumes all date and times entered, where entered in UTC. This will unfortunately shifted all date and times by the number of hours your old timezone was offset from UTC. But please keep in mind that storing date/times in UTC is a good habit and all new date and times entered correct with not shift.

WP User Level Timezone

its work for me

Allows the site-level timezone to be changed at the user profile level
