how to provide your own timestamp for log4net

Question

I'm trying to provide a Logger using a queue system and Timer to to reduce logging time on my main thread. However I would like to capture the time in which a log message was created instead of when the log message was written. While I could add the timestamp to the message, I would like the option to provide the timestamp to log4net so that I can use the pattern provider to format the written log message.

If providing the timestamp value is not possible. A way to easily format the message pattern before logging would be great.

For example:

<param name="ConversionPattern" value="%d [%t] %-5p %c %m%n" />

This might be a little late now, but there is code for a sample asynchronous appender here
