PHP-time-ago is a simple composer plugin that i created in 2009.
I was doing a bit of Ruby On Rails work and they had this feature natively. I needed this when i worked on PHP projects as well, so i copied their project spec and implemented it.
For many years, it mainly supported php 5.4 and no “external” committers helped.
Then a fellow github’er named Killmenot wanted to add the project to composer in 2014 and the rest is history 🙂
The project has had a few major iterations, where the entire library has been rewritten. It is now in version 3.2 and has a total of 43 contributors.
