* Date format: The date format character may be followed by a date format
* specifier enclosed between braces. For example, %%d{%%H:%%M:%%S,%%l} or %%d{%%d %%m %%Y %%H:%%M:%%S,%%l}.
* If no date format specifier is given then the following format is used:
* "Wed Jan 02 02:03:55 1980". The date format specifier admits the same syntax
* as the ANSI C function strftime, with 1 addition. The addition is the specifier
* %%l for milliseconds, padded with zeros to make 3 digits.</li>

* <li><b>%%n</b> - the platform specific line separator</li>
* <li><b>%%p</b> - the priority</li>
* <li><b>%%r</b> - milliseconds since this layout was created.</li>
* <li><b>%%R</b> - seconds since Jan 1, 1970</li>
