10.8.1 Setting the Time and Date

The Time Format field affects how times are displayed and entered throughout the controller. When 24 Hour For- mat is selected in this field, the hours are displayed and entered as a number from 0 to 23. When 12 Hour Format is selected, the hours are displayed and entered as a num- ber from 1 to 12; an A or a P at the end of the time signi- fies whether the time is A.M. or P.M.

Table 10-6shows some times as how they would appear in both formats.

Time	12 Hour Format	24 Hour Format
7:15 a.m.	7:15:00A	7:15:00
12:00 noon	12:00:00P	12:00:00

To select a time format, select either 12 or 24 hour using the  (LOOK UP) tab.

Active Date

The Active Date shows the current Julian date in the format that was chosen in the Date Format field. For secu- rity reasons, the Active Date cannot be set to a date earlier in time than the current date without assistance from Emerson Retail Solutions Technical Service (1-800-829- 2724).

Active Time

The Active Time is the current time in the controller’s internal clock. This time may be changed by entering the new time in the Active Time field.

When a new time is entered in the Active Time field, it is sent across the network and changed on all device clocks so that all devices can remain synchronized.

Time Zone

Time zone is where the time zone of the E2 is entered. Each time zone is represented by a time zone offset that corresponds to the amount each time zone must add or subtract from Greenwich Mean Time (GMT) to get the correct local time. Choose the time zone by using the

(LOOK UP) tab.

Time Server

Set this field to Yes or No depending on whether you would like to use SNTP (simple network time protocol) for synchronizing the E2 clock.

SNTP ensures accurate synchronization to the milli- second of computer clock times. If the E2 time is off by 5
