>From a `hdrchk'[*] run, checking for POSIX90 compliance

	*** Starting time.h
	Missing: extern char    *tzname[];
	*** Completed time.h

I don't have a copy of POSIX90, (or POSIX96 or FIPS) handy to refer to,
but I suspect adding an extern declaration will restore POSIX 
compliance for this header.  `tzname' seems present in the C lib.
