Finally had some time, and have made an updated version of the patch.
OpenSSL 1.0.2 doens't expose a function for getting the timestamp, so the patch
instead resorts to the older trick of getting the timestamp by inspecing the
diff against the UNIX epoch. When doing this, OpenSSL internally use the same
function which later in 1.1.1 was exported for getting the timestamp.
The attached version passes ssl tests for me on 1.0.2 through OpenSSL Git HEAD.
