EvaluatorService at Mac App Store analyse

Improve your productivity by calculating dates and expressions while you write. EvaluatorService allows you to evaluate simple date arithmetics, arithmetic expressions and PERL script snippets. It does this by publishing two services. These are available in almost any app that deals with text, including Mail, Safari and iChat. Its more versatile and significantly faster than changing to another calendar or calculator app. Please note, that the service requires an Admin or Standard account.
