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
