I need to find the time zone for the entries.

I have seen olson database and geonames, i was lost with olson database. couldnt find anything useful.

is there any web site i can access the time zone information based on country, region, city?

Thanks.

Did you have a look at this here...the timezone database is in the public domain.

If you can geocode your address to a latitude/longitude pair, you can give those coordinates plus a datetime to DRT Engine and get back a timezone offset.
