Dear list, the “LuaMeTaTeX Reference Manual” describes that the command line argument "--nodates" removes time dependent information in the output file. I’m afraid it doesn’t work. "\enabledirectives[backend.date=no]" doesn’t work either. This is really useful to be able to generate the exact PDF output (from a hashing point of view). Am I missing something or have I hit a bug? Many thanks for your help, Pablo -- http://www.ousia.tk
