I don't agree with 1).
But agree with 2) .
Here is an example:
data have;

run;
proc quantlife data=have seed=1268;
class group;
model T*Status(0) = group / quantile=(0.25 0.5);
run;

proc lifetest data=have;
strata group;
time T*Status(0);
run;
Here 183-2204=-2021 . is the same as PROC QUANTLIFE .
