System Tab
Time and Date
Use the
Time and Date
page to change the system’s internal clock and calendar.
Click the Refresh button to view the current time. Enter a new time and click the Change button to
set the clock/calendar. Use the same string format observed when changing time/date.
To apply Daylight Saving Time:
Select the rules as needed.
Select the Is in effect now checkbox if Daylight Saving Time is currently in effect and
select the Is enabled checkbox to enable Daylight Saving Time.
Click the Update button.
The time and date are maintained in the battery-backed real-time clock chip. Daylight saving time
settings are saved in the configuration file. To retain the daylight saving time settings through a
power cycle, save the configuration file.
The scheduler may reference the astronomical clock instead of time of day. To set the astronomical
clock, set local time and enter the location information. North is positive for latitude, and east is
positive (west is negative) for longitude.
Time zone is offset from GMT, 0 through 24, moving west around the world. As an example,
Chicago is at la41.83, longitude -87.75, time zone +6. Time zones for the Banner devices
are set up with west of GMT as positive numbers.
Sunrise and sunset calculations are typically within one to two minutes of those calculated by the
US Naval Observatory. Click
US Geological Survey
to go to a website useful for looking up latitude
and longitude of almost any US location.
