Only ONE raster should be returned for a particular time instant. Each image has a start and end time, and the end time of one image is the beginning of the next. Each image's time range spans 24 days. There are about 30 of these images in the catalog, spanning over a period of about 2.5 years. The attached picture (in the above post) of the attribute table might help you to see the date structure.
So simply put, only one raster should be returned for a particular time instant. 95% of the time I do NOT get even one raster back (when I should)... but 5% of the time I will get one (can be at any time interval, not necessarily the same one when it does show).
Hope that makes sense!
Thanks!!!
