Allow for docker timestamps with timezone offsets (#4073)

Docker prefers to use UTC time when making images/containers,
but it's happy to parse non-UTC times too. It will then pass those on in its
output.

DateTimeFormatter.ISO_OFFSET_DATE_TIME accepts a superset of what
DateTimeFormatter.ISO_INSTANT accepts, so replace use of
ISO_INSTANT with ISO_OFFSET_DATE_TIME.
