Indicate how frequently you want the storage system to contact the time daemon server:
hourly—Synchronize every hour. This is the default setting.
multihourly—Synchronize every six hours.
daily—Synchronize every day at midnight
You can also use the command line to specify a custom synchronization schedule. See the Data ONTAP System Administration Guide for details.
To avoid overburdening the time server, Data ONTAP randomly selects the exact time of the synchronization within a 20-minute window.
