Hi Pari,

> tshark -o column.format: ""No.",  
Skip the space between <column.format:> <""No.",>
This will give the same error: tshark: Invalid -o flag "column.format:"

I don't know.
You can use the option -E header=y|n only when -T fields are selected.

Take a look at:
http://anonsvn.wireshark.org/wireshark/trunk/epan/column.c

"%Yt",		/* 1) COL_ABS_DATE_TIME */
"%At",		/* 2) COL_ABS_TIME */

"%Tt",		/* 11) COL_DELTA_TIME */
"%dct",		/* 12) COL_DELTA_CONV_TIME */
"%Gt",		/* 13) COL_DELTA_TIME_DIS */

"%Rt",		/* 49) COL_REL_TIME */
"%rct",		/* 50) COL_REL_CONV_TIME */

"%t",		/* 58) COL_CLS_TIME */

You can use more than one time format:
$ tshark -o column.format:""No.", "%m", "Time", "%Yt", "Time", "%Tt"" -r
test.pcap

rejected tcp connection, established tcp connection etc
In Wireshark you can take a look at:
- Analyze > Expert Info Composite > Chats:
- Statistics > Conversations > TCP

Hope this helps
