I'm seeing different PR_CLIENT_SUBMIT_TIME values when I'm not
expecting it. Our software depends on these times being the same, at
least down to the second.

Here's an example: If I send myself an email message and compare the
PR_CLIENT_SUBMIT_TIME from the message in my Sent Items folder to the
message in my Inbox, they are different. When my company had a
simpler Exchange 2007 configuration, these differences were apparently
less than one second. Now that we have Exchange 2010 with a separate
client access server (I don't know all these details), I'm seeing
differences between the times over over a second. I'm not sure the
Exchange server change is the difference, but it seems that way at the
moment.

I thought that the PR_CLIENT_SUBMIT_TIME was set when the client
submitted the message and it never changed. Can someone help me
explain this behavior?
