Yeah.. cf should be a few times faster than bro-cut for busy log files, especially if the only thing you are doing is converting the timestamp.
It has an optimization that bro-cut doesn't have yet for avoiding converting timestamps if the current one is the same second as the previous one.

If you are using both tools though and only extracting a few fields, piping bro-cut to cf should be faster than piping cf to bro-cut.

I'm not sure why converting the timestamp is so important though.   What are you doing with the data once you convert the timestamps?
