Thank you for clarification, I forgot that fact. In this case everything is fine: the first state is in second() and the second one in first(). So delta() _is_ consistent with the usual X' + DELTA = X" [...] > when I got negative delta's I incorrectly blamed it to the negative > TOD clock (we know clocks tick backwards, how else would we claim > "time is running out" ;-) Well, time is a scalar not a vector (the later would be a good reason for "time flies"). In my pipeline is still to find reasons why time is not reversible -- there are scientist who say in limited systems it is but real world is not limited. Our world is a dissipative system and if this holds true for time too then the Delta *is* negative. <G> BTW: Greetings to Magnelia N. Ciao.....Mike
