Using tf.exe, you can get a specific version using its time and date:

 tf get /version:"D:02/08/2008 1:00:00 AM"

The DateTime format that you use should be one of the formats supported by the .Net framework. So, D2008-02-08T01:00 works, while D2008-02-08T1:00 will return an error, TF10145: The version specification is not in a supported date or time format.
