    #  that follows it in column-aligned output - means that we can't change 
    #  just <hostname> to VARIANT-HOSTNAME but <hostname> *with* padding to
    #  VARIANT-HOSTNAME with fixed width padding. Another padding issues comes
    #  from that summer and winter timezones have different widths and therefore
    #  different paddings. Although the timezone is devarianted the spacing is
    #  not. This only seems to be a problem on the end of the line because dates
    #  are always in the last column.
