The downloaded EPG seems to have been a bit erratic recently.  It is
creating a new file to download each day, but the contents are not
always updated.  I wrote myself a bit of script to get the timestamp
from the XML inside the file so that I can tell the difference:

  xmldate=`gzip -cd freeview.xml.gz | xmlstarlet sel -t -m "//tv" -v
"@date"`

And this gets the downloaded file timestamp in the same format:

  string1=`stat -c %y freeview.xml.gz | sed -e 's/-//g' -e 's/://g' -e
's/ //g'`
  filedate=${string1:0:14}

There is probably a better way to do that, so if anyone has any better
ideas, feel free to post them.  I am not much of a bash hacker yet.

I have yet to put this together into my epg script so that I can fall
back on epgsnoop when the downloaded EPG is out of date, but I hope to
find the time to do that soon.
