Timelines are sometimes a real challenge, especially with parallel plot action. I’ve heard authors complain about time zones while I’ve had some situations in my science fiction with characters on entirely different planets or even traveling at relativistic or warp speeds in different timeframes!
Some stories require more precision than others with regard to what day or time it might be. If it doesn’t matter, then all you have to watch for, if you don’t write scenes in chronological order, is that they’re in the proper sequence. If you require more accuracy, one thing you can do is put the supposed date (or perhaps even the time) at the beginning of each scene, even if you erase it when you’re ready to go to press. Then you can tell at a glance if it’s in the proper place.
