I sometimes use PowerShell to create files or logs that include the date or time. My preference is to write dates and times from greatest to smallest value. I also prefer to use the hyphen as a delimiter because it is filename friendly.
Here are the three most frequently used Get-Date -Format specifiers that I use and their formatted result:
1 2 3 4 5 6 | PS D:\> Get-Date -Format yyyy-MM-dd 2016-06-08 PS D:\> Get-Date -Format HH-mm-ss 09-23-07 PS D:\> Get-Date -Format s | foreach {$_ -replace ":", "-"} 2016-06-08T09-23-07 |
When writing scripts, I often create these three variables that I may use throughout the rest of my script.
1 2 3 4 5 6 7 8 9 10 | # Dates: Get Date and Time $Date = Get-Date -Format yyyy-MM-dd $Year = Get-Date -Format yyyy $Month = Get-Date -Format MM $Day = Get-Date -Format dd $Hour = Get-Date -Format HH $Minute = Get-Date -Format mm $Second = Get-Date -Format ss $Time = Get-Date -Format HH-mm-ss $TimeStamp = Get-Date -Format s | foreach {$_ -replace ":", "-"} |
