I don't see how index on 'datetime' can cause the error you describe.

>What are your feelings regarding this error? Do you feel that an index on a datetime would cause this error? I had made several changes prior to getting this error, but this change made the most sense. Everything else was pretty minor. We've been running the software for about a day now without any errors, but I don't know enough or understand enough about this error to be confident it has gone away. I really respect your opinion so any thoughts are appreciated.
