Wrong time when replying e-mail

When replying a message, the e-mailclient generates a message:

This goes only wrong when replying the e-mail. Not when forwaring.

When comparing the code from 1.38 with 1.37, i see something changed in the function SendMessageHeaders() in smtp_message.php
-$date = date("r");
+$date=date("D, d M Y H:i:s T");
When using version 1.37 the problem was solved!

How to fix this issue with te new version?

Hello Sjake,

It seems your email client is interpreting the time zone information in an unexpected way.

Can you tell what is the email client that you use?

Apple Mail and Microsot Outlook give the wrong dates. Gmail webclient has the correct date.

I have an e-mail message which you can use to see the issue. I could e-mail it you as an attachment.

Hello Sjake,

I tracked down the changes done to the smtp_message_class and the format used to set the Date: header was something that was changed in 2006.

So I wonder if the issues is due to the timezone not be correctly set in your server on which you run PHP.

Can you please send me a message to mlemos at acm dot org (replace the at and dot words by @ and .), so I can analyse what the headers show?

If you can set the body with the following PHP code it would be even better.

$body = "Date() time: ".date("D, d M Y H:i:s T")." strftime("%a, %d %b %Y %H:%M:%S %Z") time: ".strftime("%Z");

I e-mailed you the message.

This seems to solve the probleem:

$email_message=new \smtp_message_class;
$email_message->SetHeader('date',date("r"));

Hello Sjake,

I just updated the make to the default date header value be compliant with RFC 2822 like it was suggested by your fix.

Thank you for your collaboration.
