• src/index.js:391-571 (handler)

  The handler function for the 'get_current_time' tool. It parses input arguments, computes current time and offset date in multiple formats (ISO, slash, Chinese, timestamp, full), weekdays, builds comprehensive date info, generates travel date suggestions and hotel stay suggestions, optionally generates future dates list, and returns JSON stringified result.
