System Time and Date
The commands in this chapter configure time values on the system, either using the Dell Networking 
operating software, 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, refer to the “Network Time Protocol” section of the Management chapter 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.
