Introduction to ciscocm.dst-updater.imp.2023c-el7-00.14.0.1.cop.sha512

This cryptographic integrity-validated update package delivers critical Daylight Saving Time (DST) rule adjustments for Cisco’s Collaboration System 14.0.1 deployments. Designed to address 2023-2024 global timezone changes across 47 countries, it ensures accurate time synchronization in Unified Communications Manager (CUCM) scheduling features and call detail records.

The “_2023c-el7” suffix indicates third-quarter 2023 DST updates for Red Hat Enterprise Linux 7-based systems, while SHA512 verification guarantees tamper-proof deployment – a mandatory compliance requirement for Cisco Collaboration 14.x security protocols. This Component Offload Package (COP) resolves time-related discrepancies in conference bridges, voicemail timestamping, and automated report generation.
