    Maybe it was thought of as an offset from the unit (character null)
    like in ETA+5 minutes (expected time of arrival was passed five minutes
    ago - an euphemism for beeing 5 minutes late).

    But that makes me wonder if there was planed something like U-nnnn
    (characters before the unit)...
