While I don't specifically remember "time based" capture, I have performed captures based on a source or destination IP address on the AIP-SSM modules. They are saved on the module in pcap format. This is a standard packet capture format used by any packet sniffer, such as Wireshark (free) http://www.wireshark.org/
Download the pcap and open with Wireshark. Make sure you try out the "follow TCP stream" option in Wireshark, it's great for following a single session.
