The server should not be doing any translation of times. It should be
assumed that what is sent to the server is being sent as UTC. The
addition of the --utc flags facilitates this. If the --utc flag is
specified, then the --first-time passed is assumed to be already
UTC and will not undergo a conversion. If it is not passed, the
--first-time arg will be converted based on the the localtime of the
client, then sent as UTC.
