Convert datetime string to valid DateTime Item OR to unix time

Hello -

Need some help or pointers to achieve the following.:

I have a string item that represents a date and time in the following format (UTC) -> 201902231400. Now, I need to be able to display it in Habpanel as hh:mm (local time). To the best of my awareness, I have to either transform the string to a valid datetime object or to unix time to be able to use the angularjs date filters such as: {{ date_expression | date : format : timezone}}.

How would I do this?



I moved this to the Habpanel topic as what you are all in seems to be about that.
