This is required for platforms like Windows, that fail to parse the date otherwise. Also, the system manufacturer should not be set to the same value as the board manufacturer for the Type 1 strings, as, on the Raspberry Pi, this is not representative of the actual manufacturer of the system, which is the Raspberry Pi Foundation always. It should be noted that we do not expect other compilers than ones using a __DATE__ format similar to gcc's to be used for the foreseeable future.
