I needed to convert the date from the WMIC command output so I added a block to the code (using a copy anyway for other reasons). it is small enough to customize and here is a small customization (which can probably be improved). I wanted to have a "better" way of determining up time - converting the boot time then taking the delta seemed to be a simple solution. FYI - Win32::GetTickCount was returning 13 days (in ms) on my machine which has been up for 150something days. using this change and time() function to get a delta produced a correct result. 

    # WMIC (Windows command line) Date output format from `wmic os get
+ lastbootuptime`

    (($yr, $mon, $day, $hr, $min, $sec) =
    /^
      (\d{4})             # year
      (\d\d)              # numerical month
      (\d\d)              # day
      (\d\d)              # Hour
      (\d\d)              # Min
      (\d\d)              # Sec
    /x)
