This post is to help you out in finding UpTime of one or more computers also you can pass file as its input parameter . Most of the time, the Powershell console might not fit all the required output columns. By default, the ordering of the columns are based on the width of an output data. The best way is to manage it through Custom Formatting or Grid View. This example will show an output in all three formats.
