Here is a small problem, that is, natural day time across the actual day time, there may be yesterday's time does not show yesterday, and shown as hh:mm, so the test came to the door, asked to change, will be 2 minutes-24 hours of conditions to 2 minutes-today.

So here's the need to change

* No display in 2 minutes
* 2 minutes-Today hh:mm
* Yesterday hh:mm yesterday
* The day before yesterday hh:mm
* This year MM:DD hh:mm
* Last year MM:DD hh:mm
* Mm:dd hh:mm years ago
* Farther Yyyy:MM:DD hh:mm

This is not much of a problem, the question is in the year of the situation, 2015-01-01 00:01.001 of the first three minutes to accept the message, that is, 2014-12-31 should be shown as yesterday or last year. If the information is received more than the time, how to display.

After some tearing force, finally finalized, here for the product again, the requirements of product Ligue Ah, as the ultimate version exists.
