Description: Time columns in mysql with "24:00:00" in them return 36:00 AM when using the TIME_FORMAT function in the following way: select TIME_FORMAT("24:00:00", '%l:%i %p'); So, it appears that the %l argument returns a nonsensical hour of the day. How to repeat: select TIME_FORMAT("24:00:00", '%l:%i %p'); Suggested fix: this worked in previous versions. it correctly interpreted 24:00:00 as "12:00 AM", which was the same as "00:00:00".
