These are represented using an NSString, NSNumber, and NSDate object respectively.
Ask any Ruby developer, especially one with a background in Java, C or C , and they’ll tell you just how much better their life is since discovering Ruby.
There are many other languages that allow direct access to information about dates from their date classes, but Date (sadly) does not.
It safely works only in the Unix time offsets through the methods for building dates and remains calendar agnostic. Sometimes, we want to work with dates based on their date components (like year, month, day, etc) at a more abstract level. ####Time Ago No date library would be complete without the ability to quickly make an NSString based on how much earlier a date is than now. These "time ago" strings come in a long and short form, with the latter closely resembling Twitter. Pull requests close faster than issues (merged or rejected).
