BM/tdx-guest/tdx_mem_test.sh, in function memory_accepted_time(). It seems that $actual_time is always 0?
$SECONDS is 0, so that $actual_time is always 0.
Is this a bug for this testcase ?

@hongyuni Any comments ?

Thanks for your query @monokuma-zhuo

$SECONDS is a special built-in variable that keeps track of the number of seconds that have elapsed since the shell was started (here SECONDS=0 reset it, then we can call it as the start point), so actual_time=$SECONDS got a real number of seconds when meet the above if condition. In short, I don't see a bug here and it works well in my regular regression test.
