So today/tonight/sometime is leap second day. I’m not too sure when it is, exactly. Why? Because I don’t need to:
Jun 30 14:43:09 stratum1 lantime[1850]: Normal Operation Jun 30 14:43:17 stratum1 lantime[1850]: Leap second announced Jun 30 14:44:12 stratum1 ntpd[2172]: synchronized to PPS(0), stratum 0 Jun 30 14:44:13 stratum1 lantime[1467]: NTP sync to PPS
My timeserver knows. Firmware updates applied, leap seconds announced, music festivals to go to.
