Corrected format specifier for expectedSecondsFromGMT. Already did this in the week date tests, but I forgot to do it here.
Implemented flaky tests for flaky behavior: defaulting time-only strings to the current date.

This will probably be the first thing to be refactored: dateComponentsFromString:: should only return components found in the string. Filling in anything should be left to dateFromString::.
Added a test case for this test class's private escaping method, just to keep the code coverage numbers up.
Added tests to ensure strict parsing of variously sloppy dates returns nil. Both fail.
Strictness tests now pass.
Test parsing a date from a substring of another string. These fail for at least a couple of reasons.
Shorter, probably faster, and certainly more Unicode-aware whitespace-skipping. Fixes one cause of test failures (strlen returns zero) and makes this loop much faster than it was when we were using chars.
Include Z, when it appears, in the range of the date substring. Fixes the substring test failures.
Test that a string that doesn't contain a recognizable date gives us a range of { NSNotFound, 0 }. Boosts our coverage a bit.
Added a test case for forthcoming automatic memory-warning handling.
purgeGlobalCaches is now private.
Implemented automatic response to memory warnings.

This would fix the failure of the last relevant test assertion, but another failure (caches don't get warmed after purge) stands in the way.

At any rate, fixes #24.
Re-create the cache if it's been purged.

Fixes the last remaining memory-warning-related test failure. Refs #24.
Moved ivars from interface to implementation. Fixes #28.
Moved this comment up above the other two methods to which it applies.
Unchecking the time-only test cases in both targets, since these won't be fixed until after 0.7. Refs #30.
This global variable should be declared const.
Declare ISO8601DateFormat using NS_ENUM. Fixes #25.
Use %tu for ISO8601DateFormat (NSUInteger) values. Refs #25.
Updating the copyright in the formatter class files.
