This is more a "Seekers of Perl Testers", but I figure giving the issue more exposure helps us to better determine whether it's a problem or just a testing fluke:
Matt Sergeant is looking for testers of Time::Piece on Windows. The failures on the CPAN testers are from people I don't know and who don't seem to be too eager to be contacted, so I'm putting out a call for more testers of Time::Piece on Windows. I've already contacted him, but for me, Time::Piece 1.16 passes its tests. This is with Strawberry Perl 5.10.0, gcc 3.4.5 and dmake.
So, if you want to, please do a test of Time::Piece, and if the tests fail for you (or don't), report your Perl+Compiler+OS configuration either here or to Matt directly. If you get the distribution to fail, that would be even better, because Matt thinks he has a fix for the failure, but first he wants to reproduce it.
