Question

Assuming I have a unix timestamp in PHP. How can I round my php timestamp to the nearest minute? E.g. 16:45:00 as opposed to 16:45:34?

Thanks for your help! 🙂

Answer 1

If the timestamp is a Unix style timestamp, simply

$rounded = round($time/60)*60;

If it is the style you indicated, you can simply convert it to a Unix style timestamp and back

$rounded = date('H:i:s', round(strtotime('16:45:34')/60)*60);

round() is used as a simple way of ensuring it rounds to x for values between x - 0.5 <= x < x + 0.5. If you always wanted to always round down (like indicated) you could use floor() or the modulo function

$rounded = floor($time/60)*60;
//or
$rounded = time() - time() % 60;
