Subject: [PATCH 03/12] timesyncd: fix calculation of transmit time
The kernel timestamp (recv_time) is made earlier than current time
(now_ts), use the timestamp captured before sending packet directly.

Subject: [PATCH 05/12] timesyncd: check root distance
NTPv4 servers don't reply with unsynchronized status when they lost
synchronization, they only keep increasing the root dispersion and it's
up to the client to decide at which point they no longer consider it
synchronized.
Ignore replies with root distance over 5 seconds.

Subject: [PATCH 07/12] timesyncd: wait before reconnecting to first server
When all servers are exhausted, wait for one poll interval before trying
to connect again to the first server in the list. Also, keep increasing
the polling interval to make sure a client not getting any valid replies
will not send requests to any server more frequently than is allowed by
the maximum polling interval.
