tzN

tzN is a label that appears in various software documentation and data schemas to denote a time zone identifier or offset, but it does not correspond to a single, universally recognized standard. The exact meaning of N is context-dependent; tzN is typically used as a placeholder that should be substituted with a real time zone value by the implementing system or dataset.

In practice, tzN may function as a template key, a configuration parameter, or a field in sample data. Depending on the project, N can indicate a specific time zone choice, a numeric offset from UTC, or an index into a list of available zones. Because tzN is not standardized, its interpretation should be derived from the surrounding documentation or source code where it appears.

Relation to established time zone standards: the IANA time zone database (tz database) uses named zone identifiers such as region-based strings rather than generic placeholders like tzN. Therefore tzN should not be treated as a replacement for standard zone names; it is better understood as a provisional label used during development, testing, or templating.

If you encounter tzN in a repository or data file, consult project-specific docs or the source code to determine what N represents in that context. In absence of guidance, treat tzN as a non-final value that requires substitution before deployment.
