DateTime formatting with Log4Net
I want to display a timestamp (HH: mm: ss) in a log file that is written using Log4Net. I want this value to be in central time, but I don't want the offset to appear. Ideally I would like to read <HH:mm:ss> CT
. Right now my config is set up like this: %date{HH:mm:sszzz}
which produces this <HH:mm:ss>-05:00
. What would be the correct format specifier to create this timestamp format?

As stuartd said, you cannot format DateTime with timezones natively. However, you can create a custom PatternLayoutConverter
one that will use whatever rendering you want in the method Convert
. For reference, here's a Convert method for DatePatternConverter
:
// log4net.Layout.Pattern.DatePatternConverter
protected override void Convert(TextWriter writer, LoggingEvent loggingEvent)
{
try
{
this.m_dateFormatter.FormatDate(loggingEvent.TimeStamp, writer);
}
catch (Exception exception)
{
LogLog.Error("DatePatternConverter: Error occurred while converting date.", exception);
}
}
The field is m_dateFormatter
initialized with parameters that you can pass to them by implementing the interface IOptionHandler
.
Once you have the converter, add it to your layout by declaring it inside the layout tag
<layout ...>
<converter>
<name value="myDateWithTimeZone" />
<type value="MyApp.LogConverters.MyConverter" />
</converter>
<!-- rest of the layout -->
</layout>
