I’m really struggling to understand the problem - what does out of sync here mean - especially when you are talking about a max 500ms. ntp clock drift can already be as bad as 500ms and if you need something tighter, then you may have already gone the gps route. Either way I can’t imagine anyone building a system that has less than a 500ms tolerance for any arbitrary computer on the internet. At the very least special relativity is going to be one the first road blocks you face in trying to get perfect universal time sync

From a purely academic perspective, it means from noon preceding a leap second to noon after the leap second there's a difference between UTC and what google (and anyone else who does smears) reports as the time. If you really hated yourself and were trying to use timestamps from conflicting sources to order transactions in a database, for example, this could mess up the order of your transactions which could have all sorts of fun consequences.
