16353	Sever Clock Drift	daneroo		"MacOS Sierra Host - Virtualbox Version 5.1.12 r112440 (Qt5.6.2)

Problem on both:

  Guest: ubuntu/xenial64 - 16.04


  Guest: boot2docker (docker-machine create -d virtualbox)

This does not seem to be related to other tickets I found.


Here are some examples:


30 seconds on guest -- 1min40 real time
{{{
ubuntu@ubuntu-xenial:~$ 
while true; do echo $(date -u -Iseconds) == $(curl --silent http://www.timeapi.org/utc/now) ;sleep 10; done
2017-01-04T02:48:35+00:00 == 2017-01-04T03:02:31+00:00
2017-01-04T02:48:46+00:00 == 2017-01-04T03:02:49+00:00
2017-01-04T02:48:56+00:00 == 2017-01-04T03:03:06+00:00
2017-01-04T02:49:06+00:00 == 2017-01-04T03:03:23+00:00
}}}

And here is another: 17 seconds on guest --> 30 seconds on host (real time)
{{{
daniel@darwin:~$ while true; do echo $(docker-machine ssh dev date) == $(date); sleep 10; done
Wed Jan 4 03:01:28 UTC 2017 == Tue 3 Jan 2017 22:06:10 EST
Wed Jan 4 03:01:32 UTC 2017 == Tue 3 Jan 2017 22:06:20 EST
Wed Jan 4 03:01:38 UTC 2017 == Tue 3 Jan 2017 22:06:31 EST
Wed Jan 4 03:01:45 UTC 2017 == Tue 3 Jan 2017 22:06:41 EST
}}}
