Sending emails from an AS/400 using Java - problem with apparenttime of sending

Dear all

I am completely stumped by this.

I have a bit of code that both I and one of my customers use for sending 
spool files to Domino as emails in a nicely formatted manner (using a MIME 
HTML part).

It all works beautifully, except that the date that comes up on the email 
is always 11 hours early!

If I send an email into Domino using SNDDST this does not happen - but 
SNDDST won't do for this.

Same problem on V5R1 (me) and V5R2 (customer) and in JDK 1.3 (me) and 
1.1.8 (customer). I also get the same problem when I run the same code on 
Linux (sending to a non-Domino destination). There appears to be nothing 
in the code that is making any attempt to set a date/time, and the log of 
the conversation with the SMTP server shows the correct date/time.

It's definitely nothing to do with job dates.

Has anyone else come up against this? I can attach the relevant bits of 
the code if necessary.

Thanks

Mandy
