Hi,
In libguile/Makefile there is a call to date(1) for recording the build
stamp as so:
@BUILD_DATE="$${SOURCE_DATE_EPOCH:-`date '+%s'`}" ; \
echo ' { "buildstamp", "'`date -u +'%Y-%m-%d %T' -d
@$$BUILD_DATE`'" }, \' >> libpath.tmp
The -d flag doesn't necessarily mean the same thing across different
operating systems, e.g on macOS it means "Set the kernel's value for
daylight saving time." vs the coreutils version which means "display
time described by STRING, not 'now'"
The command errors but the build continues so it is non-fatal which is
perhaps why it has gone undetected?
