confusing `dateAtStartOfMonth` and `dateAtEndOfMonth`

[azu]

dateAtStartOfMonth means 1st day of the month.
It is not 00:00 of 1st day, but hard to know intuitively.

We imagine following action about dateAtStartOfMonth.

NSDate *startOfMonth = [[date dateAtStartOfMonth] dateAtStartOfDay];

Therefore, I would be better off [[date dateAtStartOfMonth] dateAtStartOfDay] as dateAtStartOfMonth.

Agree. The naming may be misleading.

During my test, now, actual time is 2017-04-24 10:12:34, then, dateAtStartOfMonth is 2017-04-01 10:12:34.

You may call another method dateAtStartOfDay to get 00:00:00 of the day.

There are many other methods that return a value without 00:00:00 in this category.
