SFO-bound flights are the slower direction by about 60 minutes in our estimate: the route runs partly 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
DUBEurope/Dublin — UTC+0 now; UTC+0 standard time, UTC+1 during daylight saving time
DifferenceDublin is 7 hours ahead of San Francisco today.

Jet lag, flying SFO → DUB. Your body clock has to move 7 hours earlier, like an eastward trip. A common rule of thumb is that the body clock adjusts by roughly one time zone a day, so expect up to about 7 days to fully adjust. Shifting earlier (as here) is usually the harder direction; morning daylight at the destination helps. Flying the other way, the shift is reversed.
