- Remove the redundant TC_STR_RELEASE_DATE define from Common/Tcdefs.h - Add preprocessor helpers to convert TC_RELEASE_DATE_YEAR/MONTH/DAY into the same "Month Day, Year" wide string used by TC_STR_RELEASED_BY - Update source_date_epoch.sh to derive SOURCE_DATE_EPOCH from the three numeric date defines only, removing the string-date parsing fallback

# before probing Git so symlinked build paths still use the checkout HEAD,
