Time difference

[Drinky]

I was recently asked how to work out the time difference between two timestamps so I thought i'd post the answer here.

function time_dif($ts1=0,$ts2=0){
	
	if ($ts1 < $ts2){$temp = $ts1;$ts1 = $ts2;$ts2 = $temp;}
	
	$difference = $ts1 - $ts2;
	
	$seconds = $difference % 60;
	$total_minutes = (int)($difference / 60);
	$minutes = $total_minutes % 60;
	$total_hours = (int)($total_minutes / 60);

	if ($seconds < 10){$seconds = "0".$seconds;}
	if ($minutes < 10){$minutes = "0".$minutes;}
	if ($total_hours < 10){$total_hours = "0".$total_hours;}
	
	return "$total_hours:$minutes:$seconds";
}

An equally effective approach with less processing time. Just though I would share since I too, was asked about this today.

function how_long_time($to, $from) {
    return sprintf('<b>Start Time:</b> %s<br><b>End Time:</b> %s<br><b>Elapsed:</b> %02d:%02d:%02d',
                    date("m/d/y g:i:s a", $to),
                    date("m/d/y g:i:s a", $from),
                    number_format(floor(($to - $from) / 3600), 0),
                    number_format(floor(($to - $from) / 60), 0),
                    number_format(($to - $from)%60, 0)
                    );
    }

Slight bug there freddy, when given the values

45667 and 14400

you code returns 08:521:07

see http://www.guntrisoft.com/dev/james/...667&val2=14400

although yours is a shed load cleaner than mine at doing it.

Ah I see nice call, I better fix that up right away

Sorted

function how_long_time($to, $from) {
    return sprintf('<b>Start Time:</b> %s<br><b>End Time:</b> %s<br><b>Elapsed:</b> %02d:%02d:%02d',
                    date("m/d/y g:i:s a", $to),
                    date("m/d/y g:i:s a", $from),
                    number_format(floor(($to - $from) / 3600), 0),
                    number_format(floor(($to - $from) / 60)%60, 0),
                    number_format(($to - $from)%60, 0)
                    );
    }
