Lets see if travis supports these php versions
Travis doesn't have PHP 5.5.10 (yet), so for now we're just adding it to
allowed_failures.
I really need a .travis.yml validator so i don't always commit incorrect
configuration.
Is this a spacing thing? lint.travis didn't seem to catch it.
The dash was missing.
First fix for #87.
PHP 5.5.10 seems to automatically convert GMT to UTC.
Another fix for #87.
Updated changelog
PHP 5.6 on travis does not yet have the changes PHP 5.5.10 has.

Assuming these changes will come in the future for the PHP 5.6 branch,
we're marking PHP 5.6 as an allowed failure until it's there.
Bumped version.

Fallbacks for missing timezones from PHP 5.5.10
