The Google search box can perform calculations and conversions involving math, units of measure, physical constants, and currency conversion.
A function that seems to be missing is the capability to convert times and dates between time zones.
Google does return your local time if you enter the keyword: "time", and it will also display localized time if, for example, you enter the search keywords: "time france".
However currently the following searches fail - they do not display times.
5:00 PM New York time in Rome
7:30 AM Paris is what time in Munich
10:00 PM Chicago in Geneva
In my opinion, Google calculator could be enhanced by including a simple time zone conversion function.
