I recently saw a patch to compensate for the 1000/1024 ratio,
HZ being 1000 nowadays. I'm not sure if it is already in test2.
It wasn't in test1. There is a similar compensation for 100/128
in case HZ == 100. Search for HZ == 100 in kernel/timer.c in
second_overflow()

I'm not sure what this fix does does but 2 minutes per hour is close to
1000/1024 ratio.
