I'm puzzled by this. If they isolate their networks how are they
expecting to use NTP?

NTP only needs libeay32.dll so I think they made a mistake in including

You can view the function calls by running depends.exe on the dll which
will tell you what functions can be called inside the DLL.

The OpenSSL project is developed outside of the US in order to get
around these laws and the source code is available everywhere so these
laws and regulations have no real practical effect except to reduce the
ability of American companies to compete in this market. That doesn't
help you of course, but that's the reality. You can of course get a
subsidiary outside the US obtain and ship the software, particularly as
Meinberg is a German company and not a US one, though I don't know if
the regulations also prevent that. As usual consult a lawyer.

What I can tell you is that BIND also uses OpenSSL and vendors ship that
everywhere. So if Unisys ships BIND then if can mostly like ship NTP as
well under the same conditions.
