(Perl) 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.

use chilkat();

$email = chilkat::CkEmail->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() . "\r\n";

# We can also get the Date header like this:
print "Date: " . $email->getHeaderField("Date") . "\r\n";

# Load a .eml into the email object:
$success = $email->LoadEml("myEmlFiles/someEmail.eml");
if ($success != 1) {
    print $email->lastErrorText() . "\r\n";
    exit;
}

# Show the Date that was in the .eml
print "Date: " . $email->emailDateStr() . "\r\n";

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

$dateTime = chilkat::CkDateTime->new();

$dateTime->SetFromCurrentSystemTime();

$success = $email->SetDt($dateTime);
if ($success != 1) {
    print $email->lastErrorText() . "\r\n";
    exit;
}

# Now show that the Date is the current system time:
print "Date: " . $email->emailDateStr() . "\r\n";
print "Date: " . $email->getHeaderField("Date") . "\r\n";
