Countdown timer in a static block with values from admin config

Question

I want to create a widget/static block with a countdown to the next shipment.

The shipment times should be changeable from the admin config, so I assume using PHP or PHTML are my options. (even though you can put JS code directly in a block, I believe it is not possible to call the values from config that way)

How do I make my static block execute a PHP code?

Edit

This is what I have:

app\design\frontend\default\default\template\test.phtml

<?php

echo "test";

Content of my static block:

{{block type="core/template" template="test.phtml"}}

The block doesn't display anything, what am I missing?

If you want to display system config value in static block you can use this code directly in static block -

{{config path="your_section/group/field"}}

Or if you want to execute a php code in static block then the best way is to add your php code in a phtml file and then call that phtml file in static block using

{{block type="your_module/your_block" template="your_template_path.phtml"}}
