Low PHP Time Limit

I am trying to import a theme in Wordpress but it doesn’t let me do that because Time limit value is too low in the server sided php. It should be 300 or 600 but it is actually 20 and I can’t install the demo themes!

Please help me…

Here is the screenshot


In order to import demos, your server must meet the requirements listed below.
If the import doesn’t work, you should contact your web hosting provider and ask them to adjust your server configuration to meet the recommended settings.

The time limit is low, but each account gets more than enough CPU power to install anything in under 20 seconds. Just try to ignore the warning and install it anyways, I’m pretty sure it will work.
