Hi mythies,

since I try to add nxtvepg(.sf.net) as a source for the xmltv-data I needed to 
make mythfilldatabase aware of timeoffsets in the data (given as <programm 
start="20021118150800 +0100" ...>). Therefore i programmed a patch for 
programms/mythfilldatabase/filldata.cpp.

You only need to add a settingskey "str TIMEoffset=+0100" with your local 
offset (in hours). If you don't set this key, everything should work as 
before.

This is, of course, only tested on my system, so could you please verify that 
this is working? 


take care, have fun
/christian

PS.: This is not the nicest code, but I tried to keep it easy readable, like 
the other code of mythtv :-)
