Re: [hobbit] Hobbit 4.2 - bb2 ack list has strange date -bug, patch

[Alan Sparks <asparks (at) doublesparks.net>]

This turns out to be a bug in Hobbit on x86_64.  Problem appears to be
that a time value read from the acknowledge.log by bbgen is read into a
shorter integer than is allocated as a time_t value (and that allocation
is not initialized)... so sometimes random bits are included, and skew
the time way into the future.

I solved the problem with the following patch:
