i need to copy the contents of this log file starting from "starting update" till "update completed" into another file. these lines will be displayed almost 20 to 30 times in a day but i need to search for a specific duration say 6pm to 11pm and i need to copy for this duration irrespective of number of times the string are displayed.

kproplog
KPROPLOG(8) System Manager's Manual KPROPLOG(8)
NAME
kproplog - display the contents of the Kerberos principal update log
SYNOPSIS
kproplog [-h] [-e num]
DESCRIPTION
The kproplog command displays the contents of the Kerberos principal update log to standard output. It can be used to keep track of the
incremental updates to the principal database, when enabled. The update log file contains the update log maintained by the kadmind process
on the master KDC server and the kpropd process on the slave KDC servers. When updates occur, they are logged to this file. Subsequently
any KDC slave configured for incremental updates will request the current data from the master KDC and update their principal.ulog file
with any updates returned.
The kproplog command can only be run on a KDC server by someone with privileges comparable to the superuser. It will display update
entries for that server only.
If no options are specified, the summary of the update log is displayed. If invoked on the master, all of the update entries are also dis-
played. When invoked on a slave KDC server, only a summary of the updates are displayed, which includes the serial number of the last
update received and the associated time stamp of the last update.
OPTIONS
-h Display a summary of the update log. This information includes the database version number, state of the database, the number of
updates in the log, the time stamp of the first and last update, and the version number of the first and last update entry.
-e num Display the last num update entries in the log. This is useful when debugging synchronization between KDC servers.
-v Display individual attributes per update. An example of the output generated for one entry:
Update Entry
Update serial # : 4
Update operation : Add
Update principal : test@EXAMPLE.COM
Update size : 424
Update committed : True
Update time stamp : Fri Feb 20 23:37:42 2004
Attributes changed : 6
