Problem resolved...
The Google Form "Date" option does a nice job of making sure that it is in the acceptable format for Autocrat and other scripts, but for some reason it is struggling with the "new" daylight savings dates. It was only processing incorrectly those entries that fall within the window of the new daylight savings date and the old daylight savings date change. Outside of this window the requests are processing correctly.
A-ha moment while typing...
***Error was found when I went into script editor. For some reason it had selected timezone central - Mexico City. Changed to timezone central and issue is resolved.***
