tv_grab_na_dd gets listings in GMT.  I assume by the difference
you indicated that you are EDT.  To correct this you need to
add the line "timezone: -0400" to your config file for XMLTV
(should be located in ~/.mythtv).  Of course, this will only work
for the next 6 months or so when the offset will change to
"timezone: -0500". (the timezone setting assumes you have
the latest na_dd grabber, since it is a recent feature change).

I think XMLTV in general is due to switch to GMT for all grabbers
at some point and the na_dd grabber is just telegraphing this
change.  I haven't been checking the MythDev list lately.  Has
anyone discussed storing times internally as GMT and converting
to local time for display within Myth?  This may solve some problems
with the grabber using GMT since 8pm-Midnight gets cutoff and
I have noticed that those 4 hours may be dropped from the
schedule if  I don't update daily.

HTH!!
