Stefan Bodewig commented on COMPRESS-181:
-----------------------------------------
It doesn't look like an overflow was the reason but if you look at the
timestamp it certainly reads as if the first byte was a binary 0 by accident
(if you put an ASCII 1 in there it is identical to the timestamp of the
directory).
In any case the resulting timestamp is not what it used to be, so using any
other timestamp would be as valid as trying to parse the rest.
