We already have some default behaviour defined
--
-t timeline
--timeline=timeline
Timeline from which to read log records. The default is to use the
value in startseg, if that is specified; otherwise, the default is 1.
--
So, if startseg is not provided, choose the earliest file in the
default timeline (given by -t 1 when specified).
