[Bro] binpac to bro script types

Well, I think you're on the right track. You need to do something like
this line in smb-time.pac:

> Val* bro_ts = new Val(secs, TYPE_TIME);

The Val constructor with a type of time takes a double of seconds since
the epoch (UNIX time) and gives you the Bro script timestamp val. How
you actually convert whatever format you're working to UNIX time is up
to you and dependent on the format.

Does that make sense? If you can provide more information on how the
timestamp is actually stored, someone might be able to help figure out
how to convert it.
