Comment 2 for bug 1463868

Problem in time on nodes.

Two nodes: 3 and 4 after reboot has less time for /proc/1 that before:

* 3 -> before 1433945756, after 1433945508
* 4 -> before 1433945849, after 1433945507

But for node 1 and 2 all works fine. Before deploy we run sync time hooks.

We have 2 ways:

* change Astute reboot logic to mark node as rebooted if it return different time after reboot command for /proc/1, not especially more;
* try to find and fix source of problem why time is rollback to early after reboot.

Sync time hooks details:
