Above won't work with apache2 log entries, but as quirkasaurus said you were real close.

The issue is that unless a logs for the exact times of 16:10:00 and 16:15:00 exist you don't get anything. The following will work as long as you get a log within the 16:10 and 16:15 minutes:

Code:
awk '/15\/Dec\/2010:16:10:/, /15\/Dec\/2010:16:15:/' access_log

But better is to just cover the range (works for situations like just having entries for the 16:12 minute range):

Code:
awk '$4>"[15/Dec/2010:16:10:" && $4<"[15/Dec/2010:16:15:99"' access_log

nislog

nislog(1M)                                                System Administration Commands                                                nislog(1M)

NAME

       nislog - display the contents of the NIS+ transaction log

SYNOPSIS

       /usr/sbin/nislog [-h num | -t num]  [-v] [directory...]

DESCRIPTION

       nislog  displays  the  contents of the NIS+ server transaction log on the standard output. This command can be used to track changes in the
       namespace. The /var/nis/trans.log file contains the transaction log maintained by the NIS+ server. When updates occur, they are  logged  to
       this  file  and  then  propagated  to replicas as log transactions.  When the log is checkpointed, updates that have been propagated to the
       replicas are removed.

       The nislog command can only be run on an NIS+ server by superuser. It displays the log entries for that server only.

       If directory is not specified, the entire log is searched. Otherwise, only those logs entries that correspond to the specified  directories
       are displayed.

OPTIONS

       -h num          Display num transactions from the ``head'' of the log. If the numeric parameter is  0, only the log header is displayed.

       -t num          Display  num transactions from the ``tail'' of the log. If the numeric parameter is  0, only the log header is displayed.

       -v              Verbose mode.

FILES

       /var/nis/trans.log      transaction log

NOTES

       NIS+  might  not  be  supported in future releases of the SolarisTM Operating Environment. Tools to aid the migration from NIS+ to LDAP are
       available in the Solaris 9 operating environment. For more information, visit http://www.sun.com/directory/nisplus/transition.html.
