 I am having a program with my EIT guide data being offset by 2 hours. I am
 using a DViCO FusionHDTV5 Gold USB on Fedora Core 5. I live in Los Angeles
 and am using the DViCO to receive OTA HDTV. I am running svn trunk 10721.

 I added the follow line in EITHelper::CompleteEvent(...) to aid in
 debugging:
     VERBOSE(VB_EIT, LOC + QString("event:%1 event.start_time:%2
 localstarttime:%3 utc_offset:%4")
 .arg(event.title).arg(event.start_time).arg(starttime.toTime_t()).arg(utc_offset));

 When running the backend I get:
 2006-08-09 09:38:00.833 EITHelper: event:Fox 11 Morning News at 6 AM/Good
 Day L.A. event.start_time:839336414 localstarttime:1155294000
 utc_offset:-25200
 2006-08-09 09:38:00.885 EITHelper: event:Fox 11 Morning News at 5:00
 AM/Good Day L.A. event.start_time:839332814 localstarttime:1155290400
 utc_offset:-25200

 doing the math...
 seconds per day: 86400
 leap seconds since gps epoch: 14

 for the first show:
 based upon the eit raw data, (839336414-14-25200)%86400/60/60 = 6
 based upon the calculated local starttime: (1155294000-25200)%86400/60/60
 = 4

 for the second show:
 based upon the eit raw data, (839332814-14-25200)%86400/60/60 = 5
 based upon the calculated local starttime: (1155290400-25200)%86400/60/60
 = 3

 I believe that these should be equal. It looks like it may be something
 with the qt lib. for reference:
 # rpm -qa |grep qt
 qt-MySQL-3.3.6-0.4.fc5
 qt-3.3.6-0.4.fc5
 qt-devel-3.3.6-0.4.fc5


 Thanks, let me know if I can provide more information..
