About:
CCTZ is a C++ library that provides reliable conversions between absolute times (UTC) and civil times (local time). It leverages the IANA Time Zone Database to accurately handle time zone rules, historical changes, and daylight saving transitions. This enables developers to build robust applications that correctly manage time across different geographical regions.

Key Features:

Accurate conversions between UTC and local time
Supports IANA Time Zone Database for up-to-date rules
Handles historical time zone changes and daylight saving
C++11 compatible with no external dependencies

Use Cases:

Building applications that require precise time zone handling
Scheduling tasks across different geographical regions
Logging and auditing systems that need accurate timestamps

Alternatives:

Howard Hinnant's date library – Provides similar functionality but is part of a broader chrono extension proposal
Boost.DateTime – Part of the Boost collection, offers more features but with heavier dependencies
