Often, you might want to browse all system events around a given date. Let's say a machine crashed at 08:47, and you'd like to see all events +/? 2 minutes around that time.

Here is a script that does It for you:

$deltaminutes = 2
$delta = New-TimeSpan -Minutes $deltaminutes

$time = Read-Host -Prompt 'Enter time of event (yyyy-MM-dd HH:mm:ss or HH:mm)'

$datetime = Get-Date -Date $time
$start = $datetime - $delta
$end = $datetime + $delta

$result = @(Get-EventLog -LogName System -Before $end -After $start)
$result += Get-EventLog -LogName Application -Before $end -After $start

$result | Sort-Object -Property TimeGenerated -Descending |
  Out-GridView -Title "Events +/? $deltaminutes minutes around $datetime"
复制代码

When you run it, it asks for a time or a date and time. Next, you get back all events that occurred within 2 minutes before and after in the system and application log.
