System Time and Date
The commands in this section configure time values on the system, either using the Dell Networking OS, or the hardware, or using the
network time protocol (NTP). With NTP, the switch can act only as a client to an NTP clock host.
For more information, see “Network Time Protocol” of the Management section in the Dell Networking OS Configuration Guide.
The commands in this chapter are generally supported on Dell Networking OS with some exceptions, as notes in the Command History
fields.
