Updates and displays the system time, NTP time server settings, and NTP server status.
SYNOPSIS
time { [ ‑list | ‑modify ] | ‑usage | ‑help }
DESCRIPTION
When using an external time source to provide the Oracle FS System with the current
date and time, specify up to three external Network Time Protocol (NTP) servers
by their IP addresses. The Oracle FS System uses port 123 to
communicate with the NTP servers.
The Oracle FS System selects a
server from a list of NTP servers to be the primary NTP server. After
synchronizing with the primary server, the Oracle FS System
periodically polls the primary server. If the discrepancy between the internal
clock and time that is provided by any of the NTP servers is greater than 1000
seconds, the Oracle FS System stops
attempting to synchronize.
Important! Default Windows environments
use the Simple Network Time Protocol (SNTP) to synchronize Windows clients
to one or more domain controllers. The Oracle FS System uses the standard NTP
implementation for UNIX environments. Because SNTP and NTP are known to be
incompatible, do not attempt to use a Windows system as an NTP server
without a third party NTP service installed that is compatible with
UNIX.
Important! In mixed environments,
configure the NTP service on a UNIX system. Synchronize the domain
controllers that the Windows clients are using to the defined NTP service.
Then, synchronize the UNIX‑based clients to the NTP service. Do
not synchronize the Oracle FS System or the UNIX clients
to a Windows domain controller.
Do not run the
time ‑modify
‑dateTime command to set the internal hardware clock as the time
source unless the
Oracle FS System cannot reach any NTP
servers or any file servers. If the management network becomes unavailable or
access to the NTP service fails, disable the NTP service. Then, manually set the
time. Run the following two commands
separately.
time ‑modify ‑noNtpService
time ‑modify ‑dateTime date-and-time
Note: The GUI displays the time using the local time zone that is set on the GUI client. The CLI does not present any client-based information, including local times. All time information that is presented to you in the CLI is in Coordinated Universal Time (UTC).
SUBCOMMANDS
- ‑list
- Displays the current system time in UTC and provides information
about the Network Time Protocol (NTP) servers if external time servers are being
used. The status of each NTP server is displayed, including whether the server
is being used by the Oracle FS System.
- ‑modify
- Configures the Oracle FS System to use the
internal hardware clock or an external NTP service or configures the date and
time on the Oracle FS System.
GLOBAL OPTIONS
- ‑help
Displays command usage and additional help about the command.
- ‑usage
Returns a summary of the subcommands that are available for this command.
EXAMPLE
