Set the Email Date Header to the Current System Date/Time

Demonstrates how to set the Date header field of an email to the computer's current date/time. Note: When an email object is instantiated, the Date header field is automatically added and initialized to the current system date/time. The need to explicitly set the Date header could arise when loading an email from a .eml. Chilkat2 Perl

use strict;
use warnings;
use Chilkat2;

my $email = Chilkat2::Email->new;

# At this point, a new email object has been instantiated, and it
# already has a Date header field containing the current date/time.
print 'Date: ', $email->EmailDateStr, "\n";

# We can also get the Date header like this:
print 'Date: ', $email->GetHeaderField('Date'), "\n";

# Load a .eml into the email object:
my $success = $email->LoadEml('myEmlFiles/someEmail.eml');
if (!$success) {
    print $email->LastErrorText, "\n";
    exit;
}

# Show the Date that was in the .eml
print 'Date: ', $email->EmailDateStr, "\n";

# Now the Date header contains whatever was in the .eml
# Let's update it to the current system date/time..

my $dateTime = Chilkat2::DateTime->new;

$dateTime->SetFromCurrentSystemTime();

$success = $email->SetDt($dateTime);
if (!$success) {
    print $email->LastErrorText, "\n";
    exit;
}

# Now show that the Date is the current system time:
print 'Date: ', $email->EmailDateStr, "\n";
print 'Date: ', $email->GetHeaderField('Date'), "\n";
