docker logs --timestamps command will add an RFC3339Nano timestamp
, for example
2014-09-16T06:17:46.000000000Z, to each
log entry. To ensure that the timestamps are aligned the
nano-second part of the timestamp will be padded with zero when necessary.
docker logs --details command will add on extra attributes, such as
environment variables and labels, provided to
--log-opt when creating the
--since option shows only the container logs generated after
a given date. You can specify the date as an RFC 3339 date, a UNIX
timestamp, or a Go duration string (e.g.
3h). Besides RFC3339 date

timezone on the client will be used if you do not provide either a

seconds (aka Unix epoch or Unix time), and the optional .nanoseconds field is a
fraction of a second no more than nine digits long. You can combine the
--since option with either or both of the
