Bug #110818 for Dist-Zilla-Plugin-TemplateCJM: Invalid local time for date in time zone

Thu Dec 31 10:08:36 2015 SREZIC [...] cpan.org - Ticket created

Subject:

Invalid local time for date in time zone

In rare cases t/template.t fails which the above error message. At CPAN Testers there are currently two such fail reports: * http://www.cpantesters.org/cpan/report/7799d844-a847-11e5-a8b4-c08177a17ee9 * http://www.cpantesters.org/cpan/report/09cde3e2-af8f-11e5-ab00-9321fcd2507e My guess is that somehow date/time arithmetic during a DST transition period happened --- both reports were created between 2:00 and 3:00 local time (GMT+1), a period where at some days no valid time exists. (Note that the report date+time marks the arrival of the report at metabase, not the time of the test run).

I've noticed those, but I've been completely unable to reproduce them. I've tried changing my time zone and installed libfaketime to make the test think it's running during a transition, but it always works fine for me. If you're able to reproduce it, I'd greatly appreciate any insight you can give.

Yesterday I set up three of my smokers (TZ=Europe/Berlin, 2x freebsd, 1x linux) to do a sleep until a time between 2:00 and 3:00 and to run the test suite, and managed to create one fail report. The other two passed: freebsd9.2 smoker: ... t/template.t ........ ok ... Script done, output file is /home/cpansand/.cpan_smoke_modules_typescripts/20151231/022147.typescript 2:22 cpansand@cvrsnica-freebsd-92 (~): freebsd10.1 smoker: ...

... and last night between 2:00 and 3:00 I run the tests multiple times and had not a single fail. Just bad (resp. good) luck? Or the problem does not happen anymore in 2016?
