Colon not allowed in date format string?

[sml1990]

Hello,

It seems as though {{ "now" | date: "%Y-%m-%d %H:%M" }} renders null but {{ "now" | date: "%Y-%m-%d %H%M" }} renders just fine. Is anyone else having this issue? It seems that the colon is causing it to render null.

It seems that if you change the following within /src/Liquid.php, it fixes the problem.

Change:
'QUOTED_STRING_FILTER_ARGUMENT' => '"[^":]"|'[^\':]'',

To:
'QUOTED_STRING_FILTER_ARGUMENT' => '"[^"]"|'[^\']'',

Does anyone know the details of the original pattern and why it was used? While this seems to have solved the colon issue, I haven't yet done enough testing to see if the new pattern causes other problems.
