Well I've not looked but I guess someone did convert the tally logic to use the NEW microsecond clock so the 

11,482,061ms   is 11 seconds  482,061 micro seconds. 

Also I stick the 64 bit value for the microsecond clock into a large positive integer. 

positive64BitIntegerFor  so the 18446744070288121880 is actually negative if you convert back to a 64bit integer
and do some math to arrive at what the signed value is.
