Germany Time Converter

This tool accepts a time string and an optional source time zone, then computes the corresponding Germany local time (Europe/Berlin) using DST-aware rules. It targets developers who log and report across time zones, operations teams coordinating with German stakeholders, and data engineers normalizing timestamps for analytics. The process is: parse the input timestamp, determine the source zone, apply Berlin's DST rules, and return the Berlin-local instant with the correct offset.\\n\\nConceptually, the conversion relies on the IANA time zone database. If the input contains an explicit offset, the value is normalized to UTC and then re-offset to Europe/Berlin. When no offset is present, the tool uses the provided source_zone or defaults to UTC before applying Europe/Berlin rules. The result includes berlin_time in ISO 8601 and the associated offset, enabling precise cross-region timing.\\n\\nBenefits: single source of truth for Berlin time, consistent DST handling, and outputs ready for API consumption without UI logic. Typical use cases include log normalization, scheduling with German participants, and multi-region dashboards. The tool differentiates itself by automatic DST handling, handling of ambiguous or non-existent times during transitions, and a clean JSON-ready output.\\n\\nExamples: convert 2025-03-30T12:00:00Z to Berlin time; convert 2025-07-15T09:00:00-04:00 to Europe/Berlin; query historical DST for a past date. These demonstrate accuracy across standard, DST, and edge cases.
