The overlap falls at 5:00 PM to 6:00 PM in San Francisco, or 8:00 AM to 9:00 AM if you're in Shanghai. Because Shanghai is 15 hours ahead of San Francisco, the shared window is only about 1 hour. A fixed slot at 5:00 PM in San Francisco (8:00 AM in Shanghai) saves a lot of back-and-forth. The overlap spans the date line; in practical terms, Shanghai is on the next day compared to San Francisco. Because only San Francisco changes its clocks, the overlap above isn't fixed; expect a one-hour shift when San Francisco enters or leaves daylight saving.
