Maybe we have to re-compute age between the 2 "lfs find -btime" call to take into account the execution time of the first "lfs find -btime":

local after=$(do_facet mds1 date +%s)
local age=$((after - before + 1 + skew))cmd="$LFS find $dir -btime -${age}s -type f"

nums=$($cmd | wc -l)
expected=$(((NUMFILES + 1) * NUMDIRS))echo "Clock skew between client and server: $skew, age:$age"
[ $nums -eq $expected ] ||
        error "'$cmd' wrong: found $nums, expected $expected"expected=$(($NUMDIRS + 1))

<---- re-compute the age here 

cmd="$LFS find $dir -btime -${age}s -type d"
nums=$($cmd | wc -l)
[ $nums -eq $expected ] ||
        error "'$cmd' wrong: found $nums, expected $expected"

FYI,

I hit a fail for this test on a multi-node test cluster and fixed it by installing chrony which can sync the time to the same on all the nodes.
