Gary Gregory commented on LANG-400:
-----------------------------------

I always ask this when [lang] and date features are mentioned: Would Joda-Time fit your needs now?

>                 Key: LANG-400
>                 URL: https://issues.apache.org/jira/browse/LANG-400
>             Project: Commons Lang
>          Issue Type: New Feature
>    Affects Versions: 2.3
>            Reporter: Paul Benedict
>             Fix For: 2.4
>
>
> The JDK contains Date.before() and Date.after() but no time-insensitive versions exist. I am typically in the situation where TIMESTAMP columns are converted into Date instances and I need to compare dates only for business rules.
> I propose to complement DateUtils.isSameDay:
> DateUtils.isBeforeDay
> DateUtils.isAfterDay
> My private implementations convert Date to Calendar, zero-out the time elements, and then compare.
> PS: I would also deprecate isSameXXX methods in 2.4 and rename it to isEqualXXX since sameness usually implies instance equality, rather than object equality.
