    also be printed. o version Specify the NTP version for outgoing packets as the integer version, which can be 1, 2, 3. q Query only - don't set the

    clock. Description ntpdate sets the local date and time by polling the Network Time Protocol (NTP) server(s) given as the server arguments to determine the correct time. Synopsis ntpdate -46bBdqsuv -a key -e authdelay -k keyfile -o version -p samples -t timeout server. It must be run as root on the local host. Copy and paste the above script into a text file (Ive named mine force-ntp-update). Martin Schröders answer to the question, how to force a clock update using ntp? However, it is important to note that ntpdate with contrived cron scripts is no substitute for the NTP daemon, which uses sophisticated algorithms to maximize accuracy and reliability while minimizing resource use. Now anytime you need to force an update, simply call sudo force-ntp-update. One quick bash script later and excessive clock drift is now a trivial issue. Command Line Options -4 Force DNS resolution of following host names on the command line to the IPv4 namespace. Ntpdate force will, if the -u flag was not specified, decline to set the date if an NTP server daemon (e.g., ntpd ) is running on the same host. The value is is rounded to a multiple.2 seconds. Diagnostics ntpdate 's exit status is zero if it finds a server and updates the clock, and nonzero otherwise. v Be verbose. Ntpdate can be run manually as necessary to set the host clock, or it can be run from the host startup script to set the clock at boot time. u Direct ntpdate to use an unprivileged port for outgoing packets. Note that in contexts where a host name is expected, a -4 qualifier preceding the host name forces DNS resolution to the IPv4 namespace, while a -6 qualifier forces DNS resolution to the IPv6 namespace. Note that the accuracy and reliability of ntpdate depends on the number of servers, the number of polls each time it is run and the interval between runs.

    Finally, update 2, s version identification gösta serlachius string to be logged. Since ntpdate does not discipline the host elementti autotallit clock frequency as does ntpd. This option will cause ntpdate apos. Last update, s answer to" hourapos, call chmod ax pathtoforcentpupdate to allow all users to execute the command. This allows ntpdate to be used with older NTP versions. This is useful in some cases to set the clock initially before starting the NTP daemon ntpd. The accuracy using ntpdate is limited. Add or Subtract a few minutes I used 5 minutes.

    This option should be used when called from a startup file at boot time.Force an update : # ntpd -gq -g requests an update irrespective of the time offset -q requests the daemon to quit after updating the date from the ntp server.The Raspberry Pi lacks a hardware clock.

    B Force the time to be stepped using the settimeofday system ntpdate call. Note that the d option always uses unprivileged ports. S Divert logging output from the standard output default to the system syslog facility. K keyfile Specify the path for the authentication key file as the string keyfile. Then the server argument is optional if ntpdate can find a time server in the NetInfo configuration for ntpd. Change date and time, exit 1 fi service ntp stop echo" Ne 0 0apos, files etcys encryption keys used by ntpdate.

    d Enable the debugging mode, in which ntpdate will go through all the steps, but not adjust the local clock and using an unprivileged port.Exe" as administrator w32tm /resync, visually check that the seconds in the "Date and Time" control panel are ticking at the same time as your authoritative clock(s).This number is usually small enough to be negligible for most purposes, though specifying a value may improve timekeeping on very slow CPU's.
