fill out datatime field

Question

I’m trying to fill in the input datetime-local but the field is blank, I tried to command the format american and brazilian but it doesn’t come at all. in the database is stored in American format: 2017-02-20 19:19:00 and in html I try to insert like this:

<?php $date = new DateTime($situacao[0]['data_inicio']) ?>
<div class="form-group">
    <label for="txtDataInicio" class="col-sm-2 control-label">Data Inicio</label>
    <div class="col-sm-10">
        <input type="datetime-local" class="form-control" id="txtDataInicio" name="txtDataInicio" placeholder="Nome da Função" value="<?php echo (empty($situacao[0]['data_inicio']))? set_value('txtDataInicio'): $date->format('y-M-dh:m') ?>">
    </div>
</div>

on that line I have tried to format in some formats but without success.

If only to display from the database in the input, you can display directly, without using the DateTime

<?php $date = (!empty($situacao[0]['data_inicio'])) ? date('d/m/Y H:i:s', strtotime($situacao[0]['data_inicio'])) : set_value('txtDataInicio'); ?>
<div class="form-group">
    <label for="txtDataInicio" class="col-sm-2 control-label">Data Inicio</label>
    <div class="col-sm-10">
        <input type="datetime-local" class="form-control" id="txtDataInicio" name="txtDataInicio" placeholder="Nome da Função" value="<?php echo $date;?>">
    </div>
</div>

In this code it formats to the Brazilian standard dd/mm/YYYY H:i:s but you can use any standard taking into account that is already valid in the function date()
