IIS log-Greenwich mean time (GMT + 0) (Note: Beijing time is GMT + 8). To view IIS logs in China, you need to add 8 hours to the time, to switch to the local time of the server.
Note that the event log will be converted according to your time zone configuration when it is opened. That is to say, if you check other logs against the event log, you will encounter some problems, the customer told you that the time when the problem occurred is different from the time you saw in event log.
The time of other logs will not be converted.
