There is an ongoing outage on the primary CPAN mirror. It is possible to work around the issue by using MetaCPAN as a mirror.

1.1	2001-04-11	Sub-second periods now work.  Introduced
			dependency on Timer::HiRes
1.1.1	2001-05-21	Removed test for sub-second periods - too sensitive
			to system load so test returned false negative too
			often.  It does work though :-)
