@stephan_gerlachOct 20.2006 — i would do it the following way
[code=php]
$time_start="18:12";
$time_stop="19:52";

$time_start_array = explode(':',$time_start);
$time_stop_array = explode(':',$time_stop);

$start = mktime($time_start_array[0],$time_start_array[1],'00','0','0','0');
$stop = mktime($time_stop_array[0],$time_stop_array[1],'00','0','0','0');

$time = $stop-$start;

echo date('h:m',$time);
[/code]

P.S. No idea if the code will work. Haven't tested it

@stephan_gerlachOct 20.2006 — this one works. its tested now.

[code=php]
$time_start="19:12";
$time_stop="01:13";

$time_start_array = explode(':',$time_start);
$time_stop_array = explode(':',$time_stop);


$start = mktime($time_start_array[0],$time_start_array[1],'01','01','01','1999');
$stop = mktime($time_stop_array[0],$time_stop_array[1],'01','07','01','1999');

$time = $stop-$start;
echo date('H:i',$time);

[/code]

@b1122authorOct 25.2006 — Hi all/ Stephan,

After I got the time in hours and minutes.

If I want to multiple the result by 1.5 how I do it ?

say the result is 00:40.

if i multiple 2 is correct to become 01:20

but if i multiple 1.5, it become 13:00 rather then 01:00

thanks for any help/ reply

01:00 on a 12-hour clock.

Thanks for the reply.

ok, i understand the concept.

How about if the accumulation of the result is more then 24:00.

because i got the result in this format date('H:i',$time).

If the $time more then 24:00(say 24 hours 10 minutes) , i got 00:10

@so_is_thisOct 25.2006 — I noticed in one of the original posts that the date portion must have been typoed:
[CODE]$start = mktime($time_start_array[0],$time_start_array[1],'01','01','01','1999');
$stop = mktime($time_stop_array[0],$time_stop_array[1],'01',[COLOR=Red]'07'[/COLOR],'01','1999');[/CODE]

Success!
