I tested this morning and the alert was created on 3/8/2011 8:24am. The sent time on the email is 9/8/2011 9:24am.
Alerts that were created yesterday 3/7/2011 4:42pm. The sent time on the email was 8/7/2011 5:42pm.
Seems odd to me and I have other examples if interested.
I also received 13 alerts from the threads after restarting a process, 4 of them looked fine (other than the date/time issue from above) and 9 of the alerts were blank, no subject and no body in the message. Strangely enough, the date and time was correct on these messages.
