VDN Time Zone Offset interacts with other features as follows:
VDN Time Zone Offset does not apply to time calculations associated with the doy, dow and tod Variables in Vectors variable types. The variable types use the server local time.
The VDN Time Zone Offset used is the one assigned to the active VDN for the call. The active VDN follows the VDN Override rules.
The LSP and ESS servers must be synchronized with the main server system time. This ensures that if a switch over occurs to the survivability server, VDN offset is applied consistently when the vector TOD conditional steps are being processed by the survivability server.
