Because each captured frame can be a different length, normally you
would have to skip all the preceding frames to get the timestamp of
the last record.
However, a heuristic approach might be to read the header to get the
capture-length, and then read that much from the end of the file and
look for an appropriate record header ...
On the other hand, I am unaware of any code that does that.
