How long do you let yourself acclimate to time change before racing?

Wondering about those of you who have traveled internationally for swims and how long you advise being there before the swim to adjust to the time change.
Going to Switzerland in August and want to be there early enough for adjusting before a possible 8-hour swim, but not so long that I am feeling out of touch with the water.
How do you all handle this? I am desperate to buy our tickets and can't pull the trigger!
