System Time and Date
The commands in this section congure time values on the system, either using the Dell EMC 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 EMC Networking OS Conguration Guide.
The commands in this chapter are generally supported on Dell EMC Networking OS with some exceptions, as notes in the Command
History elds.
