Hi, there are a few variables which can be accessed by TeX as well as by Lua. Unfortunately the PDF creation date can only be accessed by TeX (\pdffeedback creationdate, formerly \pdfcreationdate). What I did in the past is to pass \pdfcreationdate as an argument to a Lua function from the TeX side \directlua{ dofile(kpse.find_file("printecg.lua")) texinit("\pdfcreationdate") } where texinit() is a function defined in printecg.lua. This works fine, but it would be much nicer if I could access the PDF creation date directly from the Lua side. Then the code could be more comprehensible. The PDF creation date is required in order to write the PDF/A XMP file and I'm doing this entirely in Lua. Is it feasible to add such a Lua variable (maybe 'pdf.creationdate')?
