  Echo   %yy%-%mm%-%dd%    @  %_hh%-%_min%-%_ss%
  REN "%_pathname%" "%_file%-%yy%-%mm%-%dd%@%_hh%-%_min%-%_ss%%_ext%"

This is based on the GetDate and GetTime scripts, the last line does the file rename.

Example

c:\> stampme "sample file.txt"

An alternative 'quick and dirty' way to do the same thing in one line is shown below, this does work but is less robust as the results will vary according to regional/control panel settings.

c:\> REN "sample file.txt" "* %Date:/= % %Time::=.%.*"
