For such tasks, I currently use the faketime utility program
to run the openssl command line tool in a context with the
data artificially set to the desired time in the past.

I have previously suggested that an "as of" time argument
be added to certificate and signature validation operations,
and your use case suggests the same for issuance and signing
operations as well.

In fact, it seems the general solution (in future OpenSSL
updates) would be for all operations that use the "current
time/date" to accept an alternative value of that as an
argument.
