objcopy embeds the current time and ignores SOURCE_DATE_EPOCH making the output unreproducible.
bfd
* peXXigen.c (_bfd_XXi_only_swap_filehdr_out): If inserting a timestamp, use the value held in the SOURCE_DATE_EPOCH environment variable, if it is defined.
binutils
* doc/binutils.texi (objcopy): Document change in behaviour of objcopy's --preserve-dates command line option.
ld
* pe-dll.c (fill_edata): If inserting a timestamp, use the value held in the SOURCE_DATE_EPOCH environment variable, if it is defined.
* ld.texi (--insert-timestamp): Document change in behaviour.
