This is a fork of the excellent library,
[erlang_localtime](https://github.com/dmitryme/erlang_localtime). The purpose
of this fork is specifically for compatibility with
[qdate](https://github.com/choptastic/qdate). The two are mostly compatible,
but have diverged a bit over the years. The qdate tests will not pass if the
original erlang_localtime dependency is used due to some subtle differences to
attempt to make qdate a little bit smarter.
