Reinstall <code>indicator-datetime</code>. It should be installed by default, but just in case you have removed it unknowingly, it is best to run the install command again.

<pre><code>sudo apt-get install indicator-datetime
</code></pre>

Next, we are going to reconfigure the date time:

<pre><code>sudo dpkg-reconfigure --frontend noninteractive tzdata
</code></pre>

Lastly, restart unity.

<pre><code>sudo killall unity-panel-service
</code></pre>

On my computer, Unity shows word "Time" instead of the real time.

On Ubuntu 11 (and above?) <code>/etc/timezone</code> can't be empty (and it was). This wasn't an issue on previous versions.

To regenerate the TimeZone file just do:

<pre><code>sudo dpkg-reconfigure --frontend noninteractive tzdata
</code></pre>

It works for me.

blocks|key|3910341|text|如果这不起作用，您可以尝试恢复默认设置。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3910342|在你们的团结会议上，试着重新发起这样的团结：|3910343|unity+--reset|code-block|syntax|javascript|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|J|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|K|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|L|8|@]|9|@]|A|$G|H]]]|I|$]]

If that doesn't work you can try restoring your defaults.

From your unity session, try re-launching unity like this:

<pre><code>unity --reset

If you not found Date-Time on panel then try to find out on whether its hide or not. If not then try to find out its installed or not.

If you find that Date-Time not install then you just install it.
1. apt-get install indicator-datetime
2. killall unity-panel-service

You not need to Logoff or reset Unnity. Just check on your Desktop's Right Corner.

I like Unity very much. Recently, I installed Compiz manager and Nautilus Elementary also then tried to Play. During some of my playing around, Unity's clock applet has vanished.

I want to make it show the time again. How can I do this?
