    tdf#125055: properly round fractions of seconds
    
    ... so that 2017-07-10T09:11:02.999999... becomes 2017-07-10T09:11:03,
    not 2017-07-10T09:11:02. The latter created duplicated items in pivot
    table cache previously.
    
    TODO: check what to do if the times are actually different by 100 ns?
    What Excel does then? Should we increase cache item precision?
