Configure date, time, and daylight savings
Path: Configuration > General > Date/Time > Mode
Set the time and date used by the ATS. You can change the current settings manually or through a
Network Time Protocol (NTP) Server:
Time Zone: This is your local time difference with Coordinated Universal Time (UTC), also known as
Greenwich Mean Time (GMT).
Manual Mode: Do one of the following:
• Enter the date and time for the ATS.
• Select the Apply Local Computer Time check box to apply the date and time settings of the
computer you are using.
Synchronize with NTP Server: Have an NTP (Network Time Protocol) Server define the date and time
for the ATS. By default, any ATS on the private side of StruxureWare Server obtains its time settings by
using StruxureWare as an NTP server.
• Override Manual NTP Settings: If you select this, data from other sources (typically DHCP) take
precedence over the NTP configurations you set here.
• Primary NTP Server: Enter the IP address or domain name of the primary NTP server.
• Secondary NTP Server: Enter the IP address or domain name of the secondary NTP server,
when a secondary server is available.
• Update Interval: Define, in hours, how often the ATS accesses the NTP Server for an update.
Minimum: 1; Maximum: 8760 (1 year).
• Update Using NTP Now: Initiate an immediate update of the date and time by the NTP Server.
Path: Configuration > General > Date /Time > Daylight Saving
Daylight Saving Time (DST) is disabled by default. You can enable traditional United States DST, or
enable and configure a customized daylight saving time to match how Daylight Saving Time is
implemented in your local area.
When customizing DST, the system puts the clock forward by an hour when the time and date you
specify under Start is reached, and puts the clock back an hour when the time and date you specify
under End is reached.
• If your local DST always starts or ends on the fourth occurrence of a specific weekday of a month
(e.g., the fourth Sunday), choose Fourth/Last. If a fifth Sunday occurs in that month, you should
still choose Fourth/Last.
• If your local DST always starts or ends on the last occurrence of a specific weekday of a month,
whether it is the fourth or the fifth occurrence, choose Fifth/Last.
