Yes. The timestamp is in base-10 ASCII, so there is no Y2038 problem in
the data format (it is up to the implementation to read it into a
sufficiently large time_t internally, of course).
But negative timestamps are a different story. We use "unsigned long"
internally for timestamps, and fsck will complain about it.
 We use "unsigned long", which means we are Y2038-fine on I32/LP64
systems, but not on 32-bit or IL32/LLP64 systems. I do not use
Windows, but my understanding is that LLP64 is the norm there, so it
would eventually be a problem. But since we are unsigned, it is
actually a Y2106 problem.
