If you put a 32 bit host mask (255.255.255.255) in your SNMP client allow list (hosts.allow) Big-IP will not respond.  You must remove the host mask and leave an empty value unless your client is a network address

example: 192.168.1.0 255.255.255.0. 

Normally with BSD you are required to go into single user mode prior to changing the time.  I have discovered that you can use ntpdate to correct the time in multi-user mode (A.K.A. init level 2).
