A traffic monitoring system records traffic density for the highway in front of the MathWorks headquarters using a raspberry pi with a webcam. There is Simulink code deployed to the device which writes the sum of the observed traffic density every 15 seconds to ThingSpeak channel 38629. Create a function that uses the channel ID and returns the timestamp when the traffic was highest in the last 24 hours. If there are duplicate values, return the first.
