Timezone overlap & working-hours window API

Given two IANA timezones, report the current local time and UTC offset in each, the signed hour difference, and COMPUTE the overlapping slice of a 9-17 working day shared by both zones — DST-correct offset math evaluated via Intl that an LLM cannot perform. Answers 'what time is it in Tokyo when it's noon in New York', 'how many hours ahead is London', 'overlapping working hours between two timezones', 'best meeting window across zones'.
