在PowerShell中处理日期和时间

$currentDateTime = Get-Date
Write-Output $currentDateTime

$currentDateTime = Get-Date
$formattedDateTime = $current▌teTime.ToString('yyyy-MM-dd HH:mm:ss')
Write-Output $formattedDateTime

$dateString = '2022-01-01 12:00:00'
[datetime]::ParseExact($dateString, 'yyyy-MM-dd HH:mm:ss', $null)

$date1 = Get-Date '2022-01-01'
$date2 = Get-Date '2022-01-10'
$daysDifference = ($date2 - $date1).Days
Write-Output "Days difference: $daysDifference"

$currentDateTime = Get-Date
$newDateTime = $currentDateTime.AddDays(5)
Write-Output "New date after 5 days: $newDateTime"

$date1 = Get-Date '2022-01-01'
$date2 = Get-Date '2022-01-10'

if ($date1 -lt $date2) {
    Write-Output "date1 is earlier than date2"
}
