System Time and Date

The commands in this section configure time values on the system, either using the Dell EMC Networking OS, or the hardware,

For more information, see “Network Time Protocol” of the Management section in the Dell EMC Networking OS Configuration

Guide.

The commands in this chapter are generally supported on Dell EMC Networking OS with some exceptions, as notes in the

Command History fields.
