	For those who don't want to wait for OpenVMS V7.0, my POSIXTIM V1.0
	library is now available from

	ftp://ftp.ifn.ing.tu-bs.de/vms/posixtim.zip

	This library also contains an utime() routine independent from
	POSIXTIM to set the file date.

	Note that this is the first release. Please report any bugs.
