--- Begin Message ---Package: gcc-5 Version: 5.3.1-17 Severity: normal Tags: upstream patch Control: clone -1 -2 Control: reassign -2 gcc-6 6.1.1-1 Hi, With the SOURCE_DATE_EPOCH patch from upstream, the __DATE__ and __TIME__ macros always give Jan 1 1970 00:00:00 when running the preprocessor on its own with gcc -E[1]. I believe this is because c_lex_with_flags is not called when just preprocessing (no C code needs to be lexed), so pfile->source_date_epoch stays initialised to 0, and subsequent __DATE__/__TIME__ expansions believe that the timestamp has been set to epoch 0. I have attached an alternative implementation of gcc-SOURCE_DATE_EPOCH.diff which fixes this, by initialising pfile->source_date_epoch inside libcpp when pfile is initially created.
