Counter
This plugin contains both a counter as well as a clock. The clock part lets you show the time both digitally or analog. You can choose the font, colour, spacing, if you want milliseconds etc. On the analogue clock you are able to set the length and the width. The analogue clock has no face, so you can pick your own.
The countdown part let's you pick a date and time to count down to, for instance: the first of jan at midnight. When the clock reaches that time, the time will show 00:00
