Redwood City is in the PDT (Pacific Daylight Time) timezone. When the TC is on, the timezone is on normal time again (summertime or DST expires 30 October), which is GMT-8 .
It is autumn now in the San Francisco Bay Area, which has a mild sea climate. You can expect both rain and sun, with nightly temperatures slightly cold (though well above freezing point), and mostly agreeable in daytime. You can look for yourself at the 5-day weather forecast, available in Celsius and Fahrenheit.
The local currency is USD or US Dollar (US$). Exchange rates can be found by clicking here. Cash withdrawal machines (ATMs) are quite common, also in the airports. All major credit cards are commonly used as well.
Local
power is 120 V at 60 Hz. Power plugs are of US type (#102 : 2 parallel
flat pins, plus for grounded devices a round pin) - converters are
available at any airport and your favourite world travel adapter will
always sport the #102 type plug.
Telephone plugs
are usually of the modular RJ-11 type. Where wired ethernet/802.3 is
offered, the standard modular RJ-45 is commonly used.
The
city where the TC takes place has its own website: Redwood City. The
neighbouring town is Belmont.
Quite near is the Santa Cruz
mountain range that separates the Bay from the Pacific Ocean
- in places you find here the giant Sequoia "Coast Redwood" trees. If
you rent a car, visiting the Santa Cruz range can very conveniently be
followed by hitting the Pacific Coast and driving north to San
Francisco. San Francisco itself is described in too numerous webpages,
but the wikipedia
pages are a good starting point.
There are
numerous possibilities for tours and visits in the Bay Area, and also
culture and musea are available in a wide variety. If you are a hiker
and looking for a 1 or 2 day hike - there are plenty of state parks
around which offer good possibilities. In the Santa Cruz mountains for
instance the Big Basin
Redwoods State Park. On the opposite side of the bay there
are also various parks, of which Mount
Diablo is certainly recommendable.
