'use strict';
 
var React = require('react-native');
var {
  StyleSheet,
  TouchableOpacity,
  View,
  Text,
} = React;
 
var DateTimePicker = require('react-native-datetime');
var Button = require('@remobile/react-native-simple-button');
 
module.exports = React.createClass({
  getInitialState() {
    return {
      date: new Date(),
    }
  },
  showDatePicker() {
    var date = this.state.date;
    this.picker.showDatePicker(date, (d)=>{
      this.setState({date:d});
    });
  },
  showTimePicker() {
    var date = this.state.date;
    this.picker.showTimePicker(date, (d)=>{
      this.setState({date:d});
    });
  },
  showDateTimePicker() {
    var date = this.state.date;
    this.picker.showDateTimePicker(date, (d)=>{
