I implemented it from scratch because I needed deeply customizable date/time selection widget for our React and Bootstrap powered Web-sites.
Every existing component I've tried at the moment is not tunable enough or too buggy.
This component called DateTime works like React-Bootstrap Input. For localized date and time manipulation we uses MomentJS, so we support user-defined formats of date and time for values and display.
