16422cf Include timezone in metadata validUntil value and use UTC time

    Include timezone in metadata validUntil value and use UTC time
    
    The python datetime module doesn't append the timezone in its
    isoformat() output, so add a Z indicating that the time is
    UTC time. Also generate the output using utcnow() rather than
    now() so the times line up.
