That should be cool for SharePoint Administrators. If you would like to get all log information from the ULS log of SharePoint you can use this cool snippet with Powershell and insert the needed datetimes. It will save the information in a file.
Add-PSSnapin Microsoft.SharePoint.Powershell -ErrorAction SilentlyContinue Get-SPLogEvent -StartTime "05/06/2014 16:00" -EndTime "05/06/2014 16:30" > c:\Loginformation.log
There are many more options and it is also possible to get the windows event log in the same way. Just look at the links below:
