Date difference?

[BUU]

What im trying to do, is find the difference between to dates, one in a mysql timestamp format, the other in the localtime format, in the form of seconds:minutes:hours etc. I tried to use Class::Date, but all i could get it to do was give me the number of seconds between the dates, which when i tried to get it to give me a nice string, always gave me something like '1970 january 1..', b/c it adds the seconds onto that date or something like that. None of the other modules on cpan seemed to do what i wanted, they all just appeared to be methods for deterimining a specific date in time. Anyone know of a good module or something? This is the code i came up with:

    my ($i,$d,@posttime,@difference,@t);
    my $posttime=shift;
    my @mytime=(localtime)[0..5];
    $mytime[5]+=1900;
    $mytime[4]+=1;
    for(my $i=0;$i<scalar @t;$i++){next if $i==0;$mytime[$i]=(length $
+mytime[$i]==1)?'0'.$mytime[$i]:$mytime[$i]};
    unshift @posttime,(substr "$posttime",0,4);
    for($i=4;$i<14;$i+=2){unshift @posttime,(substr "$posttime",$i,2);
+}
    if(($mytime[0]-$posttime[0])<0){$mytime[1]--;$mytime[0]+=60;}
    $difference[0]=($mytime[0]-$posttime[0]);
    if(($mytime[1]-$posttime[1])<0){$mytime[2]--;$mytime[1]+=60;}
    $difference[1]=($mytime[1]-$posttime[1]);
    if(($mytime[2]-$posttime[2])<0){$mytime[3]--;$mytime[2]+=24;}
    $difference[2]=($mytime[2]-$posttime[2]);
    if(($mytime[3]-$posttime[3])<0){$mytime[4]--;$mytime[3]+=31;}
    $difference[3]=($mytime[3]-$posttime[3]);
    if(($mytime[4]-$posttime[4])<0){$mytime[5]--;$mytime[4]+=12;}
    $difference[4]=($mytime[4]-$posttime[4]);
    $difference[5]=($mytime[5]-$posttime[5]);
    $i=0;$d='';
    my @englishtime=('second(s)','minute(s)','hour(s)','day(s)','month
+(s)','year(s)');
    #for(@difference){$d.="$_ $mytimeime[$i] ";$i++;}
    $d="[$difference[0]s:$difference[1]m:$difference[2]h - $difference
+[3]d/$difference[4]m/$difference[5]y]";
    return $d;

I know its incredibly kludgy and barely runs under use strict, which is mostly why im looking for a good module to use.
