c.getTimezoneOffset is not a function

[edhgoose]

I'm getting an error "c.getTimezoneOffset is not a function" when trying to view the demo.

I'll admit, I'm a bit behind - I'm using an old version at the moment and only able to upgrade to version 1.5 as I'm still on Symfony 2. As far as I can tell though, the issue would affect all versions.

Here's a screenshot of what I see in the gchart/demo controller:

The issue I believe is because the DataCell generates dates with [new Date](date here)[new Date] while all the templates are looking for [[[new Date]]]
