PowerCLI - Incorrect StartTime when placed in a CSV?

The StartTime is dramatically different when it is placed into a CSV.  For example:

For one user, Get-RemoteSession shows a StartTime of "Sun Jun 23 08:28:12 MDT 2013".  But when I pipe it to Export-CSV, the value shows "Mon Nov 16 15:41:05 MST 45446"

Any idea why?
