If your clock is getting out of sync the best thing would be to use an ntp server. But since that require a internet connection I wrote a small script that uses the time table transmitted by the DVB providers instead.
<pre>
{{{
#!/bin/bash
UTC=@/usr/bin/dvbsnoop UTC=`/usr/bin/dvbsnoop -N 1 0x14 | /bin/grep 'UTC_time' | /bin/cut -c27-45@ -c27-45`
date --utc --set="${UTC}"
</pre>
}}}
In order for this to work you need:
* a DVB card in your computer (obviously).
* "dvbsnoop":http://dvbsnoop.sourceforge.net/ [http://dvbsnoop.sourceforge.net/ dvbsnoop] installed.
* rights to change the clock
* to have your bios set to UTC time (and correct timezone in linux)
