Maybe you can try adding loader.argv0_override="/usr/libexec/platform-python3.6" to the manifest? I think python guesses the path from argv[0].

I tried to run the helloworld code on nodejs 14 and latest Gramine. It doesn't crash, and the log is: ``` [P1:T1:node] debug: ipf_open: handle: 0, path: 'mrenclave//hello.txt', real size:...

If you add this to CI-Example bash manifest.template, the result is correct: ``` ... loader.env.TZ = ":/etc/localtime" ... fs.mount.etc.type = "chroot" fs.mount.etc.path = "/etc" fs.mount.etc.uri = "file:/etc" ... sgx.allowed_files =...

Looking at shim_do_gettimeofday(), tz is never touched, hence the initial value 60 is always there. Is it because this argument is obsolete or a bug?
