Specify offset values in Standard Time equivalents

Last Updated : Jun 07, 2018 |

When you set up a regular schedule for a time synchronization task in Avaya Site Administration, specify an offset value that reflects the difference in local time between the client computer and a target Communication Manager location.

Avaya Site Administration uses the set time command to synchronize the Communication Manager clock time with the clock time of the Avaya Site Administration client. Avaya Site Administration always sends the set time command in Standard Time. Communication Manager checks the DST rule specified in the set time command, which is always Standard Time, and compares the Daylight Saving Rule with the existing rule. If a DST rule other than Standard Time is in effect, Communication Manager sends an error message back to Avaya Site Administration. When Avaya Site Administration receives the error message from Communication Manager, Avaya Site Administration automatically corrects the synchronization time to comply with the DST rule on the local computer and again sends the adjusted time back to Communication Manager.

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 the target Communication Manager is located in a time zone where the DST rule is in effect, convert the local time to reflect the Standard Time rule. A best practice is to always normalize Communication Manager and client times to Standard Time before you calculate offset values.

  • After you normalize the local times to their Standard Time equivalents, calculate the offset time as the difference between the local Standard Time at the client end and the local Standard Time at the Communication Manager end. This value is the offset between the client computer and Communication Manager that you specify when you use the Avaya Site Administration Time Synchronization feature.
