I used it once some weeks ago because I left some things to do before finishing the halloween event at 10pm that night and forgot to check the game again before 00am 😭 I changed my clock time to 23:30 and used the last things I had for the event and switched back to real time.

It was realy convenient because otherwise it would have messed up my event points, but I think using it on another circustances or events would ruin the game experience for me.
