What is going wrong is your two servers are 2-3 minutes apart.

If you ask person A the time, and they say "8:43" and that is the only
person available, you can choose to believe them.  If, 2 minutes later,
person A leaves and person B arrives and you ask them the same question and
they say "8:47" you can choose to believe them.

But if they are both in the room and you ask them and their answer differs
by 2 minutes, what do you do then?
