Neet Help Printing Tshark Time Value

[George Roebe <georgerroebe () live com>]

I need some help printing the time using tshark. I have a trace trace01 and I'm running the following command:
tshark -r trace01 -R "wlan.sa == xx:xx:xx:xx:xx:xx" -t e -T text -T fields -e frame.time
I need the time printed to the console from the epoch: The time in seconds since epoch (Jan 1, 1970 00:00:00), and I 
thought (according to the man page) that that's what the -t e command would do. However, it doesn't seem to work: I get 
times like
Jan 19, 2009 13:07:54.974012000

Is there any way I can get the epoch times alone printed to the screen or to a file?

Greatly appreciated.
