I'm trying to set up piped access and error logs, with "rotatelogs", as
I'm porting the configuration from Solaris box to a small cluster of
Linux VMs running RHEL 5.
We're trying to use file name patterns like:
error_log_chnuinfow3.%Y-%m-%d-%H_%M_%S.txt
The date substitutions are working, but the time of day characters come
out as zeros. An example, and some system information, are quoted below.
I originally was trying to use rotatelogs from the Red Hat httpd RPMs.
But since they are a version of httpd 2.2.3 with back-ported patches,
I then tried building the newest httpd 2.2.21 from source, off to one
side, with static support binaries.
That's the source of /usr/local/sbin/rotatelogs below. But both versions
seem to have the same symptom.
I wrote a C program to test the system strftime, and that seemed to work
as expected, but I suppose the APR library date/time library is what is
being used, making that somewhat moot.
(I'm also aware of logrotate, and the legacy server just stops and
starts the server in a nightly job that also rotates the logs in a shell
script. Others wanted to do use piped log rotation,
I'm trying to make it work.)
Any ideas?

Test of the system strftime on a similar pattern seems OK:
[lunde@chnuinfow3 ~]$ cat strftime_test.c
#include <stdio.h>
#include <time.h>
#include <stdlib.h>
#include <unistd.h>
/* gcc -ansi -Wall strftime_test.c -o strftime_test */
int main (int argc, char** argv)
{
time_t rawtime;
struct tm * timeinfo;
char buffer [80];
if(argc<2){
printf("# Usage: strftime_test <format-string>\n");
exit(0);
}
time ( &rawtime );
timeinfo = localtime ( &rawtime );
strftime (buffer,80,argv[1],timeinfo);
puts (buffer);
return 0;
}
[lunde@chnuinfow3 ~]$ ./strftime_test "%Y-%m-%d-%H_%M_%S"
