Setting the date and time
Set the date and time (Settings > System > Date and Time) so that entries in system logs and notifications have correct time stamps. The banner displays the system date and time in the format <year>-<month>-<day> <hour>:<minutes>:<seconds>.
Access the Date and Time panel by clicking on the date and time displayed in the banner or by clicking Settings > System > Date and Time.
You can set the date and time manually or configure the system to use Network Time Protocol (NTP) to obtain date and time from an available network-attached server. Using NTP allows multiple storage devices, hosts, log files, and so on to be synchronized. The NTP server address value can be an IPv4 address, IPv6 address, or FQDN. If NTP is enabled but no NTP server is present, the date and time are maintained as if NTP was not enabled.
NTP server time is provided in the UTC time scale, which provides several benefits:
- To synchronize the times and logs between storage devices installed in multiple time zones, set all the storage devices to use UTC.
- To use the local time for a storage device, set its time zone offset.
- If a time server can provide local time rather than UTC, configure the storage devices to use that time server, with no further time adjustment.
NOTE Whether NTP is enabled or disabled, the storage system does not automatically make time adjustments for Daylight Saving Time. You must make such adjustments manually by changing the time zone offset.
NOTE If you change the time zone of the secondary system in a replication set whose primary and secondary systems are in different time zones, you must restart the secondary system to enable management interfaces to show proper time values for replication operations, such as the start, end and estimated completion replication times.
