About time in Irvine
Irvine occupies part of the former Irvine Ranch in central Orange County. It was laid out as a master-planned community by the Irvine Company and incorporated as a city in 1971 — six years after the University of California, Irvine opened on land donated from the ranch in 1965.
The city's office parks house West Coast and Asia-Pacific headquarters for many technology, semiconductor, and gaming firms, so calendars here juggle a three-hour lag to the East Coast against next-day mornings in Tokyo and Seoul: a 5:00 PM call from Irvine lands at 9:00 AM the following day in Japan.
Nearby John Wayne Airport, which serves Irvine, enforces one of the strictest aircraft curfews in the country, with scheduled departures confined to Pacific-clock hours from 7:00 AM to 10:00 PM on weekdays.
