Chapter 2 PowerMonitor 1000 Unit Features
Daylight-savings Time Setup
Daylight-savings time (DST) setup is done in the Advanced Setup menu. If DST
is enabled, the power monitor internal clock advances by one hour on the start
date and hour specified, and is set back by one hour on the return date and hour
specified. The defaults represent the common DST start and return date/times in
use in the United States in 2006. The DST function also adjusts the network-
time synch offset when used.
Network Time Synchronization
Network time synchronization is available only on units equipped with the
optional Ethernet network. Set-up parameters are found in the Ethernet
communication set-up menu. The power monitor updates its time from a simple
network time protocol (SNTP) server or an anycast group of SNTP servers,
depending on setup parameter values. Network-time synchronization set-up
parameters are found in the Ethernet communication set-up menu.
