	I reproduced this behavior, and asked some questions, and looked
at the library sources, and it seems that the time() and ctime() functions
return Greenwich Mean Time (GMT), *not* local time. The fault lies with the
documentation for not reporting this little fact, and will be corrected.

If you need local time (or the machine's clock time) you can do something
with the OS Utilites and the International Utilities Package:

#include <MacTypes.h>
#include <stdio.h>
#include <OSUtil.h>
#include <IntUtilPkg.h> /* this may not be the right name? */

main()
{
	Str255 theDate, theTime;
	long secs;

	GetDateTime(&secs);
	IUDateString(secs, longDate, &theDate);
	IUTimeString(secs, TRUE, &theTime);

	printf("%s\n", &theDate);
	printf("%s\n", &theTime);
}

I haven't actually tested this, and it's not an exact replacement of the
unix time function, but it (or something like it) should work.
