Translation impact on UI
When internationalizing your apps the lengths of your strings might change drastically from language to language which need care in design your CSS accordingly and keep in mind that right to left languages also exist.
For example you design your UI so that it shows June 24, 1988 in a div that has been sized to fit it just right. And then you open your UI in Spanish. 24 de junio de 1988 just doesn’t fit in that same space anymore.
Timezones
The AngularJS date/time filter picks up the timezone settings from the browser. So depending on the timezone of the computer, different people might see different information. Neither JS nor AngularJS have any built-in support to display time with a timezone specified by the developer.
