Meridian Time and Date

The following describes how to set the time and date MANUALLY in LD 2, which you will want to do with an older PBX release.
Alternatively, you can Set the Time with NTP if available.

NOTE: With the newer releases, you must login as ADMIN2 to change the time and/or date.

Changing the time on a CS1K can impact devices and ELAN applications that derive their time from that system. Consider the implications of an incorrect time and date change before implementing the change.

Set Time and Date

Use a TTY to access LD 2 - this proceedure cannot be done from MAT or OTM.

To print the current time and date, enter:

TTAD

Example: TTAD WED 24 11 1976 15 41 49

To Set the Time And Date, enter:

STAD day month year hour min sec

Example: - look again, this is now! Copy this command.

The year may be input as a full 4-digit field or as a 2-digit short form. The 2-digit short form is assumed to be in the range 1976-2075 and the appropriate addition is made when calculating the day-of-week and leap years. Did you notice the example is NOW!?

Pentium II Cores (and newer) have a battery clock, all others need re-setting after a powerfail.

Set daily time adjustment

The time of day can be adjusted during the miidnight routines to compensate for a fast or slow system clock.

To print the current adjustment: TDTA

To set the adjustment: SDTA x y

Legend
x = 0 (negative increment) or 1 (positive increment)
y = 0-60 second adjustment in increments of 100mS

Set and print Daylight Savings Time

The daylight savings time adjustment can be programmed to take place auotmatically. Note, the system clock MUST ALREADY be set for daylight savings time to be updated. This information survives a sysload.

FWTM - Set the date and time for the clock to move forward.
BWTM - Set the date and time for the clock to move backward.
SDST - Enable or disable the automatic change.
TDST - Query the change information.

To implement these commands, use the following.

FWTM <month> <week> <day> <hour>

month = 1-(4)-12 [January-December]
week = (1)-5, L [1st-5th, L is the last week of the month]
day = (1)-7 [Sunday-Saturday]
hour = 1-(2)-22 [Midnight-11pm]

BWTM <month> <week> <day> <hour>

month = 1-(10)-12 [January-December]
week = (1)-5, L [1st-5th, L is the last week of the month]
day = (1)-7 [Sunday-Saturday]
hour = 1-(2)-22 [Midnight-11pm]

SDST ON, OFF

ON enables the automatic change capability
OFF disables the automatic change capability

TEST <CR>

The output reflects the input format to indicate the change information.
