+# time2input
+
+A helper to manage 2 time inputs with increment/decrement on second input when the first changes.
+
+## How to use
+
+`npm install time2input --save-dev` or `yarn add -D time2input`.
+
+```js
+const inputTimeChange = require('time2input');
+const beginTime = '08:00';
+const endTime = '09:00';
+const intervalInMinutes = 15;
+const thisInputIs = 'begin'; // or "end"
+const action = 'down'; // up to sum or down to substract
+const newInputTimes = inputTimeChange(beginTime, endTime, intervalInMinutes, thisInputIs, action);
+// newInputTimes = { begin: '07:45', end: '09:00' }
+```
