Issue/Introduction

Viptela performance polling fails with an Illegal time zone error when you specify deprecated three-letter abbreviations like EST instead of IANA timezone IDs

oc.log

ERROR ~~ Viptela_<engine_id>=Performance Poll [OC_SCRIPTING] Logger$error$7 -1  Illegal time zone specified: EST

Environment

Virtual Network Assurance 24.3.x, 25.4.x

Java: Version 8 and higher

Cause

Java 8+ utilizes ZoneId․of(), which requires precise IANA timezone database IDs․ Deprecated 3-letter abbreviations are ambiguous, lack Daylight Saving Time rules, and are no longer supported in modern Java environments․

Resolution

Use only IANA time zone Ids within VNA Engine configuration.

Example:

Change EST to America/New_York
