What I need to do is figure this out for more than one location at a time. I am displaying Sabbath times for several different cities around the world at once (New York, London, Paris, Jerusalem, Sydney) - i.e. a certain amount of time before sunset, different for each city and each city is in a different dst zone.

Can I do something using setlocale, to change timezones to the city I need, and then use date(I)? Or does date(I) always work only for the US? And what exactly does setlocale change? I couldn't figure out from the notes on php.net.

Thanks for your help,

As an afterthought, the docs are inspecific on who's daylight savings schedule
that the function returns. There's another user submitted function in the
comments list that takes into account a specific schedule.
