Probably belongs in "Networking" because it seems a little advanced for "Newbie."

But,

Code:
tshark -r beacon.pcap -R wlan.fc.type_subtype==0x08 -T fields -e frame.time -E header=y > beacon.csv
Will get you the time stamp from beacon frames. Im sure it would be easy to convert that to a tcpdump command. Its not my idea though, original source: http://www.wireshark.org/lists/wires.../msg00099.html
