(Ruby) 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.

require '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() + "\n";

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

# Load a .eml into the email object:
success = email.LoadEml("myEmlFiles/someEmail.eml")
if (success != true)
    print email.lastErrorText() + "\n";
    exit
end

# 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..

dateTime = Chilkat::CkDateTime.new()

dateTime.SetFromCurrentSystemTime()

success = email.SetDt(dateTime)
if (success != true)
    print email.lastErrorText() + "\n";
    exit
end

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