I have modified the configuration of rsyslogd to disable RSYSLOG_TraditionalFileFormat.
But still the apache log /var/log/apache/error.log is displaying only second-precission.
Is there something else that needs to be configured?

The CustomLog directive is what controls the location and format of the Apache access log file. This directive can be placed in the server configuration file ( /etc/apache2/apache2. conf ) or in your virtual host entry. Note that defining the same CustomLog directive in both files may cause problems.
Base. Module: mod_log_config. The CustomLog directive is used to log requests to the server. A log format is specified, and the logging can optionally be made conditional on request characteristics using environment variables.
Apache uses the Common Log Format (CLF) by default, but you can specify your own format string to change the fields included in each log. You can also use the CustomLog directive to change the location of the log file.
Apache reports extensive data about your website, server, and users, but extracting that data from logs is the trick. Parsing Apache logs convert the raw text produced by Apache into fields that can be indexed, searched, and analyzed.
At http://httpd.apache.org/docs/current/mod/mod_log_config.html you see differemt time formats including mili seconds Just change from
%t
to
%{%d/%b/%Y:%T}t-%{msec_frac}t for miliseconds
or
%{%d/%b/%Y:%T}t-%{usec_frac}t for microsecs
Example: 16/Mar/2013:22:44:34-634 16/Mar/2013:22:44:34-634200
Documenation apache
%t Time the request was received, in the format [18/Sep/2011:19:18:28 -0400]. The last number indicates the timezone offset from GMT
%{format}t The time, in the form given by format, which should be in an extended strftime(3) format (potentially localized). If the format starts with begin: (default) the time is taken at the beginning of the request processing. If it starts with end: it is the time when the log entry gets written, close to the end of the request processing. In addition to the formats supported by strftime(3), the following format tokens are supported:
sec number of seconds since the Epoch
msec number of milliseconds since the Epoch
usec number of microseconds since the Epoch
msec_frac millisecond fraction
usec_frac microsecond fraction
These tokens can not be combined with each other or strftime(3) formatting in the same format string. You can use multiple %{format}t tokens instead.
