omniORB: Status of 2038 compatibility with time_t

While working on some code involving omni_thread::get_time() I was
wondering if omniORB does already support times beyond 2038?

Glancing at omni_time_t shows that it uses unsigned long internally, so
at least on 64bit linux architectures this should be good.

https://wiki.debian.org/ReleaseGoals/64bit-time has a good, but debian-
centric description of the problem.
