I'll give Apple & Onion a chance. I actually didn't catch on to the episode I saw on either CN.com or YT a while ago. Maybe something will change.
There's a number of certain times quarters aren't specified. Meaning, I see a few of when a show might end a quarter after or to, but by the next show you show it to start the next quarter later. One example is weekdays you show Gumball to end at 1:15, but Unikitty starting at 1:30, meaning nothing indicated at 1:15. I colored the times in the quote of where I noticed the missing gaps
