Check the call where the primitive primitiveDirectoryLookup   
(FileDirectory default directoryContentsFor: )
is called that invokes the platform specific code in  
sqMacUnixFileInterface.c which has the code below

sqInt dir_Lookup(char *pathString, sqInt pathStringLength, sqInt index,
/* outputs: */  char *name, sqInt *nameLength, sqInt *creationDate,  
sqInt *modificationDate,
		sqInt *isDirectory, squeakFileOffsetType *sizeIfFile)

...
   /* last change time */
   *creationDate= convertToSqueakTime(statBuf.st_ctime);
   /* modification time */
   *modificationDate= convertToSqueakTime(statBuf.st_mtime);
...

where
/*
  * [XSI] This structure is used as the second parameter to the fstat(),
  * lstat(), and stat() functions.
  */
struct stat {
	dev_t	 	st_dev;		/* [XSI] ID of device containing file */
	ino_t	  	st_ino;		/* [XSI] File serial number */
	mode_t	 	st_mode;	/* [XSI] Mode of file (see below) */
	nlink_t		st_nlink;	/* [XSI] Number of hard links */
	uid_t		st_uid;		/* [XSI] User ID of the file */
	gid_t		st_gid;		/* [XSI] Group ID of the file */
	dev_t		st_rdev;	/* [XSI] Device ID */
#ifndef _POSIX_C_SOURCE
	struct	timespec st_atimespec;	/* time of last access */
	struct	timespec st_mtimespec;	/* time of last data modification */
	struct	timespec st_ctimespec;	/* time of last status change */
#else
	time_t		st_atime;	/* [XSI] Time of last access */
	long		st_atimensec;	/* nsec of last access */
	time_t		st_mtime;	/* [XSI] Last data modification time */
	long		st_mtimensec;	/* last data modification nsec */
	time_t		st_ctime;	/* [XSI] Time of last status change */
	long		st_ctimensec;	/* nsec of last status change */
#endif
	off_t		st_size;	/* [XSI] file size, in bytes */
	blkcnt_t	st_blocks;	/* [XSI] blocks allocated for file */
	blksize_t	st_blksize;	/* [XSI] optimal blocksize for I/O */
	__uint32_t	st_flags;	/* user defined flags for file */
	__uint32_t	st_gen;		/* file generation number */
	__int32_t	st_lspare;	/* RESERVED: DO NOT USE! */
	__int64_t	st_qspare[2];	/* RESERVED: DO NOT USE! */
};

The iPhone and new OSX version has

	*creationDate = convertToSqueakTime([fileAttributes objectForKey:  
NSFileCreationDate ]);
	*modificationDate = convertToSqueakTime([fileAttributes objectForKey:  
NSFileModificationDate]);


These seem correct but I don't have a test case handy.
