I don't think this is right. For instance, on Mac, this code will run whe
chrome/common/time_format_browsertest.cc calls is. The locale would not be set. 
The test still passes, but it fails to test the code path in ICU it is suppose
to test.

+#else
   EXPECT_TRUE(setlocale(LC_ALL, locale.c_str()) != NULL) <<
       "Failed to set locale: " << locale;
+#endif
 }
 
 ScopedLocale::~ScopedLocale() {
   EXPECT_STREQ(prev_locale_.c_str(), setlocale(LC_ALL, prev_locale_.c_str()));
 }
 
 }  // namespace base
