Hi,

The 'timestamp' you are referring to is actually a relative timestamp with respect to the first frame in the capture file. Therefore your filtered capture file will always have the 0.0000 timestamp on the first frame.

Thanks,
Jaap

hi,

I am using tethereal.  I captured few packets, in which 10th packet is tcp with
timestamp 1.2436.

I set a filter for tcp and saved the filtered packets to another file.  The
resultant file the tcp packet as first packet and timestamp as 0.0000

Can someone tell me how to save the filtered packets and keep the timestamp
intact.  I want to get the timestamp 1.2436, as it is in my resultant file.

I tried the options in tethereal '-t a' and '-t r', but both resulted the same,
i.e. timestamp 0.0000

Thanks in advance.
uv.
