Slight difference in date between parole stamp and online I94

[hoping4thebest]

I recently used my EAD/AP card (based on my pending Green Card application) to re-enter the U.S after a trip on November 20th, 2013. As per the new process, I retrieved the online I-94 from the USCIS website (attached) and noticed that the “Most Recent Date of Entry” is listed as “2013 November 21” on the online I-94. The parole stamp by the officer at the port of entry on my passport, however, correctly lists the date as November 20^th, 2013. Please note that it was almost 11 PM on November 20th by the time we got through Immigration so I wonder if that is why the online I-94 has the next day’s date listed. Do I have to get this corrected (i.e the online I94 date) or is it OK? Would appreciate any feedback.
