I just pulled up one of my V3 Pro cameras (what I assume you were doing this on since you tagged the post that way). and set up a future time lapse. I note that the date change is right next to the hour change so it would be VERY easy to accidentally slide it - what I suspect you did. I thought that maybe when you set the start time to 2100 and the end time defaulted to shortly after the current time (before you set it), it did automatically change the date to the next date - else the start would be after the end time. However, that is not the case. It will allow entering an end time that is before the start time on the same date. Of course when you try to save that condition, it won’t let you save it and give an error message that the start time is later than the end time.
In other words, the software behaves exactly as it should.
BTW, in my opinion, a timelapse would be a very poor choice for fireworks. You would have been far better to set the uSD card to continuous recording. I have shot video of many professional fireworks shows over the years - both using Wyze cameras and a drone. Here’s one I shot with a V2 camera that was in the middle of the firing pit pointed straight up. This video is the last minute of the show. The finale starts about 12 seconds into the show, and yes, by the end of the video, the sound is several seconds ahead of the video (a Wyze problem many years ago).
