34 System Time and Date You can set and maintain system times and dates through the network time protocol (NTP). You can also set them through the Dell Force10 operating software (FTOS) command line interfaces (CLIs) and hardware settings. This chapter includes the following sections: • Network Time Protocol • Overview • Implementation Information • Configuring Network Time Protocol • FTOS Time and Date • Configuring Time and Date Settings • Set Daylight Savings Time Network Time Protocol Network time protocol (NTP) synchronizes timekeeping among a set of distributed time servers and clients. The protocol also coordinates time distribution in a large, diverse network with a variety of interfaces. In NTP, servers maintain the time and NTP clients synchronize with a time-serving host. NTP clients choose from among several NTP servers to determine which offers the best available source of time and the most reliable transmission of information. NTP is a fault-tolerant protocol that automatically selects the best of several available time sources to synchronize to. Multiple candidates can be combined to minimize the accumulated error. Temporarily or permanently insane time sources are detected and avoided. Dell Force10 recommends configuring NTP for the most accurate time. In FTOS, you can configure other time sources (the hardware and software clocks). System Time and Date | 595
