question for yahoo search engine marketing?

i like to list my store to yahoo search engine marketing, it tells me to
1)select a market
2)select a time zone.
when i "select a market" to japan, what time zone am i supposed to select? ex, alaska, hawaii, etc.
i just don’t get it. is it MY time zone?

confusing….

time zone u should select as per your location… it would help you track your campaign performance
