Re: Re: Current time as variable?

[einerwitzen]

it seems that they all work when the codes you gave are in one part. I tried it as

&starttime;
&stoptime;


sub starttime{
my $start = time;
sleep 5;
}

sub stoptime{
my $end = time;
my $elapsed = $end - $start;

print $elapsed;
}

and it always prints out as 1071679507 seconds

[b10m]

That is because in sub stoptime, your script doesn't know what $start is, since you only declared that in the starttime sub. Now if you'd do it like the following, it would print out 5:

my $start;
my $end;

&starttime;
&stoptime;

sub starttime{
   $start = time;
   sleep 5;
}

sub stoptime{
   $end = time;
   print $end - $start."\n";
}

Update: If you'd put "use strict;" in the beginning of your little snippet, Perl would warn you about this with: Global symbol "$start" requires explicit package name at test line 14.
