[IDV #NKA-540396]: Possible time-matching snafu



Hi Jim-

The realtime image datasets (RTIMAGES, GINIEAST, GINIWEST, GINICOMP) only save 
the last 96 images.  There will be more Visible images because they are not 
available at night.

If you are going to use multiday images, then I suggest using the IMAGEALL and 
GINIALL datasets (and NEXRCALL for radar) which go back 45 days.  You'll need 
to select an archive date when you first load in the data (just select the 
current day), but when you time match, it will select the appropriate dates.

However, if you are running the nightly build, the image matching should not 
fail, it should just match the times it has images for.  I fixed that for you a 
few weeks ago, so make sure that you use the nightly build.

Also, in tomorrow's nightly build, there is support for time matching of 
surface observations.  Note that these only go back 9 days.
