Dominik Psenner commented on LOG4NET-380:
-----------------------------------------

As far as I know .NET does convert a DateTime to the computers local time when it is deserialized. This is actually expected and I can't quite understand why log4net should try to work around that? If you wanted all timestamps to be UTC, you could still invoke http://msdn.microsoft.com/en-us/library/system.datetime.touniversaltime(v=vs.100).aspx on the machine that receives all logging events or even change the timezone of that machine to be UTC.

>             Project: Log4net
>          Issue Type: Bug
>          Components: Appenders
>    Affects Versions: 1.2.11
>         Environment: .NET 4 application on RaspberryPi (Arch Linux) with Mono 2.10.9, logging with RemoteAppender to an application on Windows 7, which uses a custom appender to add the received LoggingEvents to a collection.

> The timestamps from RemoteAppender are UTC, but the TimeStamp.Kind property is "Local".
> Both the Windows and Linux machines have their system time set to local time.
> The LoggingEvent TimeStamps that are received from the Windows machine (not going through RemoteAppender) contain local timestamps, and the LoggingEvent.TimeStamp.Kind is "Local".
> The LoggingEvent TimeSTamps that are received from the Linux machine (going through RemoteAppender) contain UTC timestamps, but the TimeStamp.Kind is "Local", not "Utc".
> If the Kind property was UTC, I could adjust the timestamps from both log event sources to match (both UTC/both Local). Unfortunately, I cannot tell the difference using just the TimeStamp field itself.
