[Orca-users] Re: Date_parse routine usage

[Blair Zajac]

Michael,

It should look something like this:

date_parse	sub {
		  my $string = $_[0];
		  $string =~ s/_/ /g;
		  return parsedate($string);
		}

The date_parse routine should be called for each line.

To debug this, try

date_parse	sub {
		  my $string = $_[0];
		  $string =~ s/_/ /g;
		  my $t = parsedate($string);
		  print "$_[0] => $t => ', scalar localtime($t), "\n";
		}
