Implementing the Time of Day Clock Synchronization feature
356 Communication Manager Guide to ACD Call Centers
Avaya Site Administration uses the
set time
command to synchronize the switch clock
time to the clock time of the Avaya Site Administration client. Avaya Site Administration
always sends the
set time
command in Standard Time. Depending on the switch
software version, one of the following results occur:
●
if the receiving switch is installed with R11 (or later), the switch checks the Daylight
Savings Rule specified in the
set time
command (which is always Standard Time),
and compares it to the existing rule in effect for the switch. If a Daylight Savings Rule
other than Standard Time is in effect at the switch, the switch adjusts the incoming
synchronization time as necessary.
●
if the receiving switch is installed with R10 or earlier, the switch checks the Daylight
Savings Rule specified in the
set time
command (which is always Standard Time),
and compares it to the existing rule in effect for the switch. If a Daylight Savings Rule
other than Standard Time is in effect at the switch, the switch sends an error message
back to Avaya Site Administration. When Avaya Site Administration receives the error
message from the switch, it automatically corrects the synchronization time to comply
with the Daylight Savings Rule on the local PC, and resends the adjusted time back to
the switch.
When you calculate offset values to use as input in the Avaya Site Administration Time
Synchronization feature, you must do the following:
●
If either the client or target switches are located in a time zone where Daylight Savings
Time rules are in effect, convert local times to reflect what the time would be if the
Standard Time rule was in effect. The best practice is to always normalize switch and
client times to Standard Time before you calculate offset values.
●
After you normalize the location times to their Standard Time equivalents (if necessary),
calculate the offset time as the difference between the local Standard Time at the client
and the local Standard Time at the switch. This value is the offset between the PC client
and switch that you specify when you use the Avaya Site Administration Time
Synchronization feature.
For an example scenario that illustrates the offset calculation method, see
Designing a
TOD clock synchronization schedule
on page 358.
Possible lag between synchronization start times on the client and
actual run times at the switch
You can set up multiple TOD clock synchronization tasks to run simultaneously on the
client PC. However, synchronization tasks are actually run in sequence. Actual
synchronization run times at the switch may vary from the run time specified on the client
by several minutes. However, the accuracy of the synchronization setting is not affected.
