Facter 4 outputs some uptime facts differently on Windows

While running puppet facts diff on Windows 10 Enterprise 32bit, Windows 2019 64 bit in Japanese and Windows 2012r2 FIPS 64 bit, I got the following output:

{

  "system_uptime.uptime": {

    "new_value": "1:3 hours",

    "old_value": "1:02 hours"

  },

  "uptime": {

    "new_value": "1:3 hours",

    "old_value": "1:02 hours"

  }

}

Note: EXCLUDE_LIST from https://github.com/puppetlabs/puppet/blob/6.x/lib/puppet/face/facts.rb#L5 needs to be manually emptied to see above results.
