Minimal, mostly statical http://clock.zone fork.
There are 4 main scripts and they all end with .php extension
because originally they were written in PHP (see mail from Igor).
In this repository they are actually shell scripts which make use of timestamp
and busybox, both installed in /busybox.
Another script is widget/digit.php used only in the Widget mode.
The additional cgi-bin/index.cgi shell script is used to generate the analog clock.
