How to find date/time stamp of the mail?

["Sharma, Ashutosh" <As...@gs.com>]

How to find out the date/time stamp of the email that is being failed to
deliver.
Let's say we send a mail via apache james. 
It fails(hard or soft failure).
I want to read the time it got failed? How to read the header or
something to find it out?

With Best Regards:
Ashutosh Sharma
