If you notice that the time logged in IIS logs does not match your server's local time, this is because IIS logs time in UTC (GMT) to conform with the W3C log format so if you are in a different time zone for example UTC -3 you will find the time 3 hours ahead in the logs.
To change that, you can choose a different log format from the IIS manager or you can convert the log file using Log Parser.
Download and install Log Parser then run the following command
LogParser.exe "SELECT DATE,TO_LOCALTIME(time) AS time,s-ip,cs-method,cs-uri-stem,cs-uri-query,s-port,cs-username,c-ip,cs(User-Agent),sc-status,sc-substatus,sc-win32-status,time-taken INTO c:\ayman\output.log FROM c:\ayman\input.log" -i:IISW3C -o:W3C
