Php: DateTime: how to set only seconds (not hours neither minutes)

Question

I have a code where I have to "round" to the lowest minute.

• 16:05:00 should become 16:05:00
• 16:05:01 should become 16:05:00
• 16:05:29 should become 16:05:00
• 16:05:30 should become 16:05:00
• 16:05:31 should become 16:05:00
• 16:05:59 should become 16:05:00

I want to use the DateTime object. There are no functions such as:

• setHours()
• setMinutes()
• setSeconds()

Here's the beginning of my code:

$my_date=DateTime::createFromFormat(
    'Y-m-d H:i:s',
    $bd_date
);  
$my_date->setTimezone(self::$TimeZone);

Now I'd like to set the "seconds" part to zero.

Do you have an elegant way of only setting minutes the way I'd like to?

Nota: I'm not looking for a solution like "divide by getTime() by 60, convert to integer, then multiply by 60". I'm looking for a generic solution to set the seconds, not only to "0".

Answer 1

Is setTime elegant?

$my_date->setTime ( $my_date->format("H"), $my_date->format("i"), $new_second_val );
$my_date->setTime ( $my_date->format("H"), $new_minute_val, $new_second_val );
// etc...

Answer 2

Just set the seconds to "00"

date_default_timezone_set('America/Sao_paulo');
$date = new DateTime();
echo $date->format('Y-m-d H:i:00');

Answer 3

Best way to set the second/minute or hour by simply using the second/minute or hour function on Carbon DateTime Object. (obvious you will need to create carbon object)

\Carbon\Carbon::now()->hour(2)->minute(20)->second(0);
