[vdr] Patch: VDR syncing time with non-root user

[Thomas Keil <tk@commedia-group.com>]

Hi everyone,

On August 14th on the vdr-portal.de a patch by Balthasar popped up to enable VDR to sync the system time as non-root user.
http://www.vdrportal.de/board/thread.php?threadid=4377&sid=&hilight=&hilightuser=0

I thought I'd post it here as well since I think it'd solve a few problems for some users here on the list.

With kind permission of balthasar:

-----------------------------------------------------------------------

1. Install the patch
2. recompile vdr
3. create a shellscript with the content
   "/usr/bin/sudo /bin/date $1"
4. enter 
    visudo "vdr ALL=(ALL) NOPASSWD: /bin/date"
5. expand runvdr to "vdr -T /path/to/setTime.script"

Have Fun!
If the path won't work for you (line breaks) you can download it at the above mentioned thread in the portal.
