About the system date and time

You can change the storage system's date and time, which are displayed in the System Status panel. It is
important to set the date and time so that entries in system logs and event-notification email messages have
correct time stamps.
You can set the date and time manually or configure the system to use Network Time Protocol (NTP) to
obtain them from a network-attached server. When NTP is enabled, and if an NTP server is available, the
system time and date can be obtained from the NTP server. This allows multiple storage devices, hosts, log
files, and so forth to be synchronized. 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 Coordinated Universal Time (UTC), which provides several options:
• If you want to synchronize the times and logs between storage devices installed in multiple time zones,
set all the storage devices to use UTC.
• If you want 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.
Whether NTP is enabled or disabled, the storage system does not automatically make time adjustments,
such as for U.S. daylight savings time. You must make such adjustments manually.
