• Details
  • The Get-Date CMDLET gets a DateTime object that represents the current date or a date that we specify
  • Get-Date CMDLET can format the date and time in several .NET and UNIX formats
  • Get-Date uses the computer’s culture settings to format the output date
  • We can use “Get-Culture” CMDLET to know the our computers date time settings
