Your module validate.pm *MUST* evaluate to true, ie., by adding 1; at the end of the module, or else it will not be loaded.

Thus your module validate.pm should look like this-
package MyValidate; # use package to declare a module
our $val;

sub val_time {
    $val = shift;
    $val = ($val =~ /^(\d{2}):(\d{2}) (am|pm)$/) ? "$1:$2 $3" : 1;
}

1;

Referring to a variable inside a package is not recommended. You could do the following instead -
package MyValidate; # use package to declare a module

sub val_time {
    my $val = shift;
    $val = ($val =~ /^(\d{2}):(\d{2}) (am|pm)$/) ? "$1:$2 $3" : 1;
    return $val; # yes this is not necessary but it clarifies my inten
+sion
}

1;
