Outlook Time stamp / time Zone problem

[Civic]

We have offices on both East and West coasts. We recently had an issue come
up where one of our East coast offices contacted support -which happened to
be out of the west coast at that time, and caused a help desk tracking
problem. The east coast office sent an email at 6:58pm (east coast local
time) requesting help. The message was received on the west coast at 3:58pm
(local time) worked on, resolved, and replied to at 4:03pm (west coast local
time), received by Lief's (east coast manager) mail box at 7:03pm (east coast
local time). Now when he came in and reviewed work orders from the previous
day it appears that this work order took 3 hours and 5 minutes to complete
-not 5 minutes, because the body of the original email with the west coast
local time stamp of 3:58pm needs to be left in for a paper trail, and his
received local time stamp of this email was 7:03pm.
Is there a way to display the sender’s original local time, or UTC, versus
the recipient's local time, for the time a message is received, when
forwarding or replying to an email -since the original needs to be included
for tracking purposes?
