Subject: [PATCH] core: Add millisecond support to ErrorLogFormat time
specifiers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
%{m} prints the timestamp in millisecond-resolution.
* include/util_time.h:
Define new AP_CTIME_OPTION_MSEC option for printing time in milliseconds
format.
* server/util_time.c (ap_recent_ctime_ex):
Handle AP_CTIME_OPTION_MSEC to print time in a millisecond format.
* server/log.c (log_ctime):
Recognize the m time option in both fast-path and composite %{...}t formats.
