How to export all System event logs of a definite time period

Question

I am working on a Windows Server 2003 SP2 with Powershell v2, and I am looking for a way to export all System event logs of a definite time period, (say, from Saturday 2000 hours to Sunday 1100 hours).

I can export all existing System logs using Get-Eventlog command to a CSV file, then copy the entries in the said time window. Though, I am looking an easier way to do this with or without using powershell.

Solution

Modify your Get-WinEvent with a filter.

$startTime = get-date "5/22/2012 20:00:00"
$endTime = get-date "5/23/2012 11:00:00"
Get-WinEvent -FilterHashtable @{Logname="System"; StartTime=$startTime; EndTime=$endTime} | Export-CSV -Path c:\temp\output.csv
