there is literally no easy and safe way to actually handle leap seconds. what happens when they need to remove one second? even for the easier case of inserted leap second, you can smear it, but what happens if there are multiple systems each smearing it at different rates? I'd strongly argue that you pretty much have to reboot all your time critical and mission critical systems during the leap second to be safe. the issue is so wide spread and complicated that they decided to stop introducing extra leap seconds so people can come up with something better in the coming decades - probably way later than the arrival of AGI.
