I like this, and think it's useful functionality. It's equivalent to -f in date(1) on FreeBSD, so we should probably support that short option > The second patch adds '--arith-format=FORMAT', where FORMAT is limited > to years/months/days/hours/minutes/seconds (%Y/%m/%d/%H/%M/%S). The idea here is to support more generic numeric deltas. I'm not sure of the interface though. Perhaps --delta-format would be clearer. Or perhaps we should just support the FreeBSD -v option to apply the adjustments, which seems more direct and would further improve compat. cheers, Pádraig
