Handle ps container created field as a time.Time

In the current code we were translating the created time
from a time.Time to a unix epoch, this was leading to a loss
of precession, and some unexpected results where the sorting
order of containers was misordered because of the precession loss.

If we pass around created as time.Time, we do not loose the precission.
