24 hours and 20 minutes between flights in Beijing Capital Airport.

I am stopping over in PEK. My flight arrives 6:10pm and my departure flight is 6:30pm the following day. That makes the time difference on the ticket 24 hours and 20 minutes. Will I require a transit visa, going by the fact that it will surely take more than that 20 minutes to get to immigration from disembarking my arrival flight.
Thank you.
