Time & locations(summer and winter time included) and currenry

Hello, I'm not so sure what language is good for these below. A page I want to add this functions on is .shtml and other pages are mostly in perl. Please suggest me. Time & location script -City name -Date, month, year, and time(seconds needed and automatic correction for summer & winter time) Currency information something like [login to view URL] on the right. Need EURO, USD, and JPY based on Russian ruble. Thanks for your bid!
