How to specifiy formating of time string in azure pipeline build number

Question

From the documention you can format the build number for the azure devops build pipeline but the formating on the time isn't working for me.

https://learn.microsoft.com/en-us/azure/devops/pipelines/process/run-number?view=azure-devops&tabs=yaml

I want something like

YY.MM.DD.MMSS

name: $(Date:yy).$(Date:MM).$(Date:dd).$(Hours)$(Minutes)

However this will generate single digits like '20.08.12.150' for 3pm. Does anyone know a way of forcing the format like the date fields so it will always be 2 chars? $(Hours:hh)$(Minutes:mm) does not work; I did try that.

Thanks

Instead of define the build number in name: of yaml file, you could add a powershell task to update the build number with command ##vso[build.updatebuildnumber]build number. Check the following example:

- task: PowerShell@2
  inputs:
    targetType: 'inline'
    script: |
      Set-TimeZone -Id "China Standard Time"
      [string] $dateTime = (Get-Date -Format 'yy.MM.dd.HHmm')
      Write-Host "Setting the name of the build to '$dateTime'."
      Write-Host "##vso[build.updatebuildnumber]$dateTime"
