time add

[Anon]

Hi

I am trying to add two time variables.

$time1 = "12:00:00";
$time2 = "11:30:00";
$time3 = date("H:i:s",mktime($time1 + $ttime2));
echo $time3;

With this i get the i get time3 = 23:system current time (minutes) :system current time (seconds).

Eg: 23:50:35

can anybody help me how do i get exact time ie 23:30:00

Thanks

$a="13:01:01";
$b="02:02:02";
$a=explode(':',$a);
$b=explode(':',$b);
$c=($a[0]3600) + ($a[1]60) +($a[2]) +($b[0]3600) + ($b[1]60) + ($b[2]);
$d=mktime(0,0,$c,1,1,1970);
echo strftime("%H:%M:%S",$d)."\n";

Note: this has a rollover at 24:00, so 23:00:00 + 04:00:00 = 03:00:00

$a = "$try1";
$slot = "15";
// Slot is 15 minutes
//$b = "try1";
$a=explode(':',$a);
//$b=explode(':',$b);
$c=($a[0]3600) + ($a[1]60) +($a[2]) + 0 + ($slot*60) + 0;
$d=mktime(0,0,$c,1,1,1970);
$e = strftime("%H:%M:%S",$d)."\n"; echo"<BR>";
echo"s = "; echo $e; echo"<BR>";
$try1 = $e; echo"<BR>";
//echo"try1 for loop = "; echo $try1;
echo"<BR>";
$try1 = $e;

}
