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