Bug: Checkout modifies the "Modify Time" of the file

Hi
I am trying to get the information of subversion files. When I do "svn
export filename" it retains the last modified time and displays it
correctly. But when I check out the file the "Modify Time" displayed is
erroneous.

Exported file details
==============
