PdfTeX adds both automatically including the time zone. Dvips adds none, thus my zwpagelayout package adds them if dvips is used. TeX does not supply at a macro level the time zone, so that the time zone is not used. Xdvipdfmx sets /CreationDate only and zwpagelayout sets /ModDate. The problem is that /CreationDate set by xdvipdfmx contains time zone while /ModDate set by the macros does not. Time information without a time zone is considered UTC. Depending on the user's time zone upon PDF/X validation it may be reported that the file was modified before it was created.
