PVG-bound flights are the slower direction by about 120 minutes in our estimate: the route runs mostly east–west through latitudes where the prevailing westerly winds at cruise height are strong, so heading east rides a tailwind and heading west fights a headwind. How we estimate it.

Time zones and jet lag

SFOAmerica/Los_Angeles — UTC−7 now; UTC−8 standard time, UTC−7 during daylight saving time
PVGAsia/Shanghai — UTC+8 now; UTC+8 all year (no daylight saving time)
DifferenceShanghai is 15 hours ahead of San Francisco today; +16 h in January and +15 h in July because daylight saving time starts and ends on different dates (or not at all).

Jet lag, flying SFO → PVG. The clock change is 15 hours, but to your body that is a shift of 9 hours the other way. Your body clock has to move 9 hours later, like a westward trip. A common rule of thumb is that the body clock adjusts by roughly one time zone a day, so expect up to about 9 days to fully adjust. Shifting later (as here) is usually the easier direction; evening daylight at the destination helps. Flying the other way, the shift is reversed.
