Specification of log fields

Dears Sirs,

I'm a recent user of Bro, so excuse me if this is a basic question...
I need to find the exact meaning of each field of log files. For example, "duration is in seconds, miliseconds...?", "difference between orig_bytes and orig_ip_bytes" and so on.

Still exist this information published in any place?

Thanks in advance!
Best regards,
Nuno.

You can usually find descriptions if you browse the script reference documentation like at [1]. Generally, for fields of type "interval" (like "duration"), the unit is seconds.
