what just happened (time went backwards?)

This f20 server has been running just fine for months. Today it became unresponsive. Couldn't ssh into it (ping ok). Not thrashing disk (disk light not continuously on). I hit the power button and rebooted. After reboot, checked /var/log/messages: Feb 25 12:06:18 nbecker7 kernel: [ 49.667251] tun: Universal TUN/TAP device driver, 1.6 Feb 25 12:06:18 nbecker7 kernel: [ 49.667254] tun: (C) 1999-2004 Max Krasnyansky <maxk(a)qualcomm.com&gt; Feb 25 12:06:18 nbecker7 kernel: [ 59.015938] Ebtables v2.0 registered Feb 25 12:06:18 nbecker7 kernel: [ 59.601221] ip6_tables: (C) 2000-2006 Netfilter Core Team Feb 25 12:06:18 nbecker7 kernel: [ 65.646938] Bridge firewalling registered Feb 25 12:06:18 nbecker7 kernel: [ 65.671316] device virbr0-nic entered promiscuous mode Feb 25 12:06:18 nbecker7 kernel: [ 66.410670] virbr0: port 1(virbr0-nic) entered listening state Feb 25 12:06:18 nbecker7 kernel: [ 66.410678] virbr0: port 1(virbr0-nic) entered listening state Feb 25 12:06:18 nbecker7 kernel: [ 66.410724] IPv6: ADDRCONF(NETDEV_UP): virbr0: link is not ready Feb 25 12:06:18 nbecker7 kernel: [ 66.668588] virbr0: port 1(virbr0-nic) entered disabled state Feb 25 12:06:54 nbecker7 kernel: [ 109.855407] fuse init (API version 7.22) Jan 8 10:48:32 nbecker7 systemd: Stopped target Graphical Interface.
