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. Lua

local chilkat = require("chilkat")

local email = chilkat.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.email_date_str)

-- We can also get the Date header like this:
print("Date: " .. email:get_header_field("Date"))

-- Load a .eml into the email object:
local success = email:load_eml("myEmlFiles/someEmail.eml")
if not success then
    print(email.last_error_text)
    return
end

-- Show the Date that was in the .eml
print("Date: " .. email.email_date_str)

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

local dateTime = chilkat.DateTime.new()

dateTime:set_from_current_system_time()

success = email:set_dt(dateTime)
if not success then
    print(email.last_error_text)
    return
end

-- Now show that the Date is the current system time:
print("Date: " .. email.email_date_str)
print("Date: " .. email:get_header_field("Date"))
