Document Library Modified Dates

Question

Hi,
We're currently moving a lot of file resources into document libraries, and one thing we've noticed is that SharePoint shows the modified date as the date the file was migrated not the actual last modified date from the file.
This is causing some users discomfort as they work from those modified dates to do their job, and now they're all the same
In Explorer View the dates show as we expect them. It's when you use the browser, or when you use Open File in Office and browse to a document library.
I wondered is there any way of adding the Last Modified Date of the file into the view of a document library?
Many Thanks,
Andrew

I'm not sure about files that have already been uploaded to SharePoint - from what I've noticed that changes the modified date on the file as well.  You can adjust it on the upload though if you script it, I've used the below script to accomplish this
in the past.  It will go through the specified folder, uploading all files, keeping folder structure intact, and adjust the SharePoint modified date/time to that of the file.
May not be exactly what you're looking for, but hopefully will help.
#change these values as required, filepath is files to upload, sitename is the sharepoint web name, listname is obvious

$listname = "<list name>"

#go through each file in the directory provided and upload
foreach ($file in (dir $fileUploadPath))
$newlocation=""; $newlocationfolder=""
