I am going to guess that what you mean is that the startup script for ntpd takes a while during bootup. Some ntp startup script first invoke ntpdate to quickly set the clock to a very close correct time and then start ntpd. It may be that ntpdate to still trying to contact an ntp peer that is not accessible with the new IP address. With redhat, there is a separate config file for ntpdate called /etc/ntp/step-tickers. Don't know about Debian. Check for something like that.

NAME
ntp-wait - Wait for ntpd to stabilize the system clock SYNOPSIS
ntp-wait [-flags] [-flag [value]] [--option-name[[=| ]value]] All arguments must be options. DESCRIPTION
ntp-wait will send at most num-tries queries to ntpd(8), sleeping for secs-between-tries after each status return that says ntpd(8) has not yet produced a synchronized and stable system clock. ntp-wait will do this quietly, unless the -v flag is provided. This can be useful at boot time, to delay the boot sequence until after ntpd -g has set the time. OPTIONS
-n number, --tries=number Number of times to check ntpd. This option takes an integer number as its argument. The default number for this option is: 100 The maximum number of times we will check ntpd to see if it has been able to synchronize and stabilize the system clock. -s secs-between-tries, --sleep=secs-between-tries How long to sleep between tries. This option takes an integer number as its argument. The default secs-between-tries for this option is: 6 We will sleep for secs-between-tries after each query of ntpd that returns "the time is not yet stable". -v, --verbose Be verbose. By default, ntp-wait is silent. With this option, ntp-wait will provide status information. -?, --help Display usage information and exit. -!, --more-help Pass the extended usage information through a pager. -v [{v|c|n --version [{v|c|n}]}] Output version of program and exit. The default mode is `v', a simple version. The `c' mode will print copyright information and `n' will print the full copyright notice. EXIT STATUS
One of the following exit values will be returned: 0 (EXIT_SUCCESS) Successful program execution. 1 (EXIT_FAILURE) The operation failed or the command syntax was not valid. 70 (EX_SOFTWARE) libopts had an internal operational error. Please report it to autogen-users@lists.sourceforge.net. Thank you. AUTHORS
