If you are still interested in a javascript api to select both date and time data, have a look at these projects which are forks of bootstrap datepicker:
-
Bootstrap Datetime Picker 1
-
Bootstrap Datetime Picker 2
The first fork is a big refactor on the parsing/formatting codebase and besides providing all views to select date/time using mouse/touch, it also has a mask option (by default) which lets the user to quickly type the date/time based on a pre-specified format.
