Here is the language from the AOIC on timing of of eFiling: Upon Submission of an efiled document, the filer will receive an email with a confirmation of their transaction. This will serve as proof of submission. A document will be considered timely submitted if efiled before midnight on or before the date on which the document is due. A document submitted electronically after midnight or on a day when the Clerks office is not open for business will, unless rejected, be file stamped as filed on the next day the clerks office is open for business. In the event the Clerk rejects a submitted document, the document will not be filed and the registered user will receive an electronic notification of the reason(s) for the rejection.
