PatternLayout dates

[Be...@rbs.com]

Hi all,

        apologies in advance if I'm being ignorant, as I'm new to this...

        I'm using log4cxx on Windows and trying to use PatternLayout to control the formatting of dates. Previously I was using log4cxx 0.9.7 and log4cxx 0.10.0 with visual c++ 7.1 and patterns such as %d{%d %b %Y %H:%M:%S:%Q} were working as expected (this one generates 29 Jan 2009 11:22:04:026).

        Recently I have been trying to use log4cxx 0.10.0 with visual c++ 9.0 and encountering https://issues.apache.org/jira/browse/LOGCXX-308. So I went to the documentation for the PatternLayout at http://logging.apache.org/log4cxx/apidocs/index.html and found this about the %d conversion character:


Used to output the date of the logging event. The date conversion specifier may be followed by a set of braces containing a date and time pattern string compatible with java.text.SimpleDateFormat, ABSOLUTE, DATE or ISO8601. For example, d{HH:mm:ss,SSS}, d{dd MMM yyyy HH:mm:ss,SSS} or d{DATE}. If no date format specifier is given then ISO8601 format is assumed.

This is very different from what worked before so I decided to test it (in log4cxx 0.10.0 and vc 7.1) and got the following results:

        Pattern                         Output

        %d{ISO8601}                             2009-01-29 11:23:38,073
        %d{ABSOLUTE}                    11:22:59,136
        %d{DATE}                                29 Jan 2009 11:19:11,448
        %d{HH:mm:ss,SSS}                        HH:mm:ss,SSS
        %d{dd MMM yyyy HH:mm:ss,SSS}    dd MMM yyyy HH:mm:ss,SSS

        Can anyone advise as to why the last two aren't giving the results expected? What I'm doing wrong? To be honest, either ISO8601 or DATE will be fine for us but I'm just puzzled as to why I can't get the last two working.

        With many thanks,

                Ben Nasatyr
