A PAM module could do this (eg LinuxPAM's pam_time).

You could potentially add code to Match to invoke an external program, 
but it would have to be done very carefully to avoid introducing a 
security problem.

Can you describe the system some more?  There might be a simple solution 
(eg you could swap sshd_config files and SIGHUP sshd from a cron job).

usually comes from bad judgement.
