Simple technique to correct the date/time of a Big-IP.  F5 will tell you to take your unit into single user mode, this is not neccessary.  I have discovered that you can update the time of an standby unit in multiuser mode.

You can update the clock in multiuser mode with ntpdate.

Syntax: ntpdate -b (time server IP/FQDN)

Manual page for ntpdate: http://www.eecis.udel.edu/~mills/ntp/html/ntpdate.html

Tested up to 4.5.10 and found this doesn't work if the clock is ahead. Single user mode seems to be the only solution.
