How do you use an image to search the Internet?

Is there a way to use search engines that index pages of twentieth years of twenty first century using the internet that uses 2012 year numeration?

• there are two different types of Internet:one that uses the year numeration of 2012(all pages are marked with this year or before)  and another one internet that uses the year numeration of the beginning of 2030th years from Christ birth. So I want to search pages in the latter one Internet using servers of the first one Internet through some proxy or somehow else.

  I'm not sure what's the point in this question, but I'll try to address some issues. Even today, and inside the "standard" Internet, there are several ways to express dates which may limit the range of valid values. Some examples are the Unix calendar (seconds since 1970) and the standard Excel calendar (which starts at January 1 1900 if I'm not mistaken). This is a binary representation, a way to store a date within a fixed binary record, either as a 32 or 64 bit integer, or a floating point number. But for Internet searches, dates are usually represented either as strings or a structured record which allow expressing any possible date. HTTP headers return the date as an string and most popular languages and frameworks convert to the structured record format, which is not limited to specific date ranges. Also, there are some situations today when you have an incomplete date (for example, is 05/12 May 2012 or May 1912?) and check the context to determine the correct information. There are ways to disambiguate the results that we can use. So we already know how to handle such situations, not perfectly, but with a good degree of precision. So my guess is that if you had access ti two Internets, and had to use one to search content into the other, it would be no big issue. A proxy could do that, and using universal intermediate representations, dates would not be a problem. Hope it helped you...
