Convert Unix timestamp to ISO 8601

Logs and databases often store time as Unix epoch seconds, but humans need ISO 8601 strings. This chain first parses the timestamp into a structured date, then converts it to the target timezone's ISO representation. Use this to normalize log timestamps for dashboards or audit trails.

What it solves

Parse a Unix epoch timestamp and convert it to a human-readable ISO 8601 string in a target timezone.
