sshd and ntpd

Let's say I have a machine that has both ntpd and openssh set to start
when the machine first boots. Further, suppose that I have an order of
operations like this

00:00:00 - sshd starts
00:00:01 - userA connects to sshd
00:00:02 - ntpd notices the clock is is 15 minutes slow and moves it forward

is it possible that the crypto routines in sshd accept would be
sensitive to the advancing system clock and kill the connection?
