If you don't have problems now, you don't even need to worry. Else just
reboot
The biggest problems I saw were with java based apps. I was running a couple
of minecraft servers for my kids and as soon as the leap second was inserted:
/var/log/kernel.log.1:Jun 30 18:59:59 archangel kernel: [268959.468848] Clock:
inserting leap second 23:59:60 UTC
minecraft servers on both boxes errored out with "Has system time changed --
unable to keep up" errors. Simply stopping and starting the applications was
_not_ enough, it required a complete reboot of the system before
minecraft_server in particular would run again.
I wondered how widespread the disruption would be, but just judging from my 2
boxes -- I knew it would be fairly widespread.
My setup was with dcron and ntp.
