<# .SYNOPSIS Converts Docker date to DateTime object .DESCRIPTION Converts Docker date to DateTime object, typically converting a string in the format of yyyy-MM-dd HH:mm:ss -0400EDT to a DateTime object. Removes timezone if found. Note: docker images and ps commands return date string that is in this format but docker history returns a value that does auto-convert to DateTime. .PARAMETER DockerDate Docker date object or string .EXAMPLE Convert-DockerDateToPSDate '2018-08-12 18:13:50 -0400 EDT' Sunday, August 12, 2018 6:13:50 PM (DateTime object) .EXAMPLE Convert-DockerDateToPSDate (Get-Date '01/01/2018 06:00:00') # already DateTime; returns as-as Monday, January 1, 2018 6:00:00 AM (DateTime object) #> function Convert-DockerDateToPSDate { #region Function parameters [CmdletBinding()] [OutputType([datetime])] param( [Parameter(Mandatory = $true)] [ValidateNotNullOrEmpty()] $DockerDate ) #endregion process { if ($DockerDate -is [DateTime]) { # return as-is Write-Verbose 'DockerDate is already [DateTime]' $DockerDate } else { # ensure it is a string $DockerDate = $DockerDate.ToString() Write-Verbose "DockerDate string passed to function: $DockerDate" $DockerDateRegex = '^(?<Date>\d\d\d\d-\d\d-\d\d)[^\d](?<Time>\d\d:\d\d:\d\d).*' Write-Verbose "RegEx used to parse this value: : $DockerDateRegex" $Matches = $null $Valid = $DockerDate -match $DockerDateRegex if ($Valid -eq $false) { Write-Verbose "Not a valid date string: $DockerDate" throw "DockerDate '$DockerDate' (no quotes) could not be parsed by regex: $DockerDateRegex" return } Write-Verbose "Calling Get-Date with combined date ($($Matches.Date)) and time ($($Matches.Time))" # create date time with values and return Get-Date ($Matches.Date + ' ' + $Matches.Time) } } } |
