DatePicker does not render time with different format

[sanzhardanybayev]

Issue

When I send formatted date value to date property, DatePicker does not render it in my format! It uses the default component's format!

Expected Behavior

Date picker renders date in my format, rather than in the default

Code

This is what I have:

 <DatePicker
          style={{ alignSelf: 'center', justifySelf: 'center' }}
          mode="date"
          date={moment.utc(this.props.chosenDate).format('L')}
          placeholder="Choose date"
          showIcon={false}
          locale={'ru'}
          format="l"
          minDate="2018-01-01"
          maxDate="2030-12-31"
          confirmBtnText="Choose"
          cancelBtnText="Cancel"
          customStyles={{
            dateInput: {
              borderWidth: 0,
              textAlign: 'center'
            }
            // ... You can check the source to find the other keys.
          }}
          onDateChange={this.props.f}
        />
