[Bonus chapter]Madmen pair with madmen

Jonathan immediately clicked on the second post about the flow of time.

OP: Since I entered the second world four weeks ago, I have a habit of setting an alarm clock on the day of return. I would enter the second world to the sound of the alarm clock, and when I returned from the second world, the alarm clock was still ringing. My alarm clock has always been a fixed nursery rhyme. Every time I return, I can hear the nursery rhyme singing to the same word, but this time when I returned, I heard the song from the alarm clock, and the lyrics had moved two words further.

5L (OP): Either my phone has a problem, the time is not synchronized, or it means what I guessed in the title—time has started to flow. I checked my phone, and the time synchronization function was not turned off, but I don't quite believe in the latter possibility. More validation is needed to prove my guess.
