No, but it does print the frame.time_delta
$ tshark -r test.pcap -T fields -E separator=, -e frame.number -e frame.time_delta

You can use the following, but it does not print the duration:
$ tshark -r test.pcap -q -z conv,eth -z conv,ip -z conv,tcp
See the man-page for more information:

Here is an example:
$ tshark -i 3 -o column.format:""No.", "%m", "Time", "%t", "Source", "%s",
"Destination", "%d", "Protocol", "%p", "srcport", "%uS", "dstport", "%uD",
"len", "%L", "Info", "%i", "tcp.flags.ack", "%Cus:tcp.flags.ack", "tcp.flags.syn",
"%Cus:tcp.flags.syn""
$ tshark -r test.pcap -o column.format:""No.", "%m", "Time", "%t", "Source",
"%s", "Destination", "%d", "Protocol", "%p", "srcport", "%uS", "dstport",
"%uD", "len", "%L", "Info", "%i", "tcp.flags.ack", "%Cus:tcp.flags.ack",
"tcp.flags.syn", "%Cus:tcp.flags.syn""
