For most applications we build, if time is relevant for more than just incidental functionality, we will typically use Joda-Time. For simply incidental functionality (e.g., a few UI elements displaying the time), we'll use the standard API.
I've not seen any home-brew date APIs outside of a few bite-size pieces of functionality. For instance, we have one custom utility that takes two times and a granularity level to render a human-readable rendering such as "2 hours, 13 minutes ago."
