I am using the date/time picker from Eonasden that you can find here. Date Time Picker
I am using HTML from the example:
According to the examples, you need to include this to..
http://momentjs.com/
It has to be after bootstrap.js, but before the datetimepickerjs like this..
bootstrap.js
datetimepickerjs
It shows it on the GitHub readme..
"Datetimepicker requires moment.js."
