How to log timestamp in EST format using log4net configuration ignoring the Server Timezone it runs on

I have added my log4net.config setting at the end of my question.
In "MyLog.txt" file I want to log timestamp in EST format using just the config file.
It should replace the %date in config below. I have seen some random articles suggest something like %d{yyyy-MM-dd HH:mm:ss}{GMT-4} but that didnt work.
I also read that Log4j has something called EnhancedPatternLayout which seems to have such date options. But Log4net has nothing equivalent.
Please share if you have some solution to show EST dynamically in Log irrespective of the Server timezone it runs on.
<appender name="ApiLoggerAppender" type="log4net.Appender.RollingFileAppender">
<lockingModel type="log4net.Appender.FileAppender+MinimalLock"/>
<file value="C:\MyLog.txt"/>
<appendToFile value="true" />
<rollingStyle value="Date" />
<datePattern value="-ddMMyyyy" />
<PreserveLogFileNameExtension value="true" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %level %logger - %message%newline" />
</layout>
</appender>

EventView Appender Log4net using C#

I want clarification on root cause of an issue. I have integrated log4net library in my C# project. I have created appender using code. FileAppender, ConsoleAppender and AdoDotnetAppender was working fine but event
var eventViewAppender = new log4net.Appender.EventLogAppender();
eventViewAppender.Threshold = Level.Error;
eventViewAppender.LogName = "MyName";
eventViewAppender.ApplicationName = "MyName";
var layout = new log4net.Layout.PatternLayout()
{
ConversionPattern = "%date{hh:mm:ss.fff} [%thread] %-5level - %message%newline"
};
eventViewAppender.Layout = layout;
layout.ActivateOptions();
log4net.Config.BasicConfigurator.Configure(eventViewAppender);
Then I took approach of having xml format configuration in app.config. I had below settings.
<appender name="EventLogAppender" type="log4net.Appender.EventLogAppender" >
<applicationName value="MyApp" />
<logName value="MyApp" />
<threshold value="ERROR" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger - %message%newline" />
</layout>
</appender>
I think both configuration should work, but unfortunately second option works while first not. If anyone had encountered similar issue and fixed it, please do let me know resolution.

Log4net - Suppress "exception" from being appended to custom "PatternLayout"

When using a custom "PatternLayout", log4net is appending the "exception" information (when present) to every log entry. I am trying to control the output of the message and stack trace information and would like to "suppress" this information. I have searched around but cannot find a way to do it. Any ideas?
Sample web.config entry (for a RollingFileAppender):
<layout type="Example.Class.CustomLog4netLayouts,Example">
<conversionPattern value="%date [%thread] [RID:%property{CLIENT_REQUESTID}]
%-5level %logger [%property{NDC}] - %cleanmessage - %cleanstack%newline" />
</layout>
Thanks

Configure the layout like this:
<layout type="Example.Class.CustomLog4netLayouts,Example">
<IgnoresException value="False" />
...
Setting IgnoresException to false tells the appender that the layout will take care of the exception. Thus you can choose not to print the stack trace.

log4net print DateTime/calling class/function on each line

Is there any way using log4net to automatically write date/time and class name/function name to the start of each logged line?

In the log4net configuration file modify Appender section by adding a PatternLayout with custom format. Following pattern will output DateTime ClassName.MethodName
<appender name="DebugOut"
type="log4net.Appender.OutputDebugStringAppender">
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date{MM/dd/yy HH:mm} %C{1}.%M" />
</layout>
</appender>
You can output fully qualified name of class by changing %C{1} to %C

Can I get log4net to append the real class name and not the generated closure class name?

I have a class that is logging from an anonymous method. I've dumbed it down to make the point...
public class SocketFlusher
{
private static readonly ILog Log = LogManager.GetLogger(typeof(SocketFlusher));
public void Flush()
{
Wait.For(timeout, () =>
{
... // work
Log.DebugFormat("{0} bytes available", socket.Available);
}
}
}
My log4net configuration is good (I've checked the log4net debug="true" output and the appender does work). My appender layout is
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%-4thread] %-5level %class{1} - %message%newline"/>
</layout>
But, my log output has that crazy auto-generated static class in it.
2011-03-21 18:10:20,053 [5 ] DEBUG SocketFlusher+<>c__DisplayClass1 - 82 bytes available
I want it to say SocketFlusher, what is the right appender layout to get this format?

You want the class name to appear in the appender output. And you're following the log4net idiom of naming your logger the name of the class...
private static readonly ILog Log = LogManager.GetLogger(typeof($CLASSNAME$));
What you want to do in the appender pattern layout is to include the %logger name pattern instead of the %class pattern.
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%-4thread] %-5level %logger{1} - %message%newline"/>
</layout>
