Consider how many temporary types should be supported

[making]

Bean Validation supports following types

• java.util.Date
• java.util.Calendar
• java.time.Instant
• java.time.LocalDate
• java.time.LocalDateTime
• java.time.LocalTime
• java.time.MonthDay
• java.time.OffsetDateTime
• java.time.OffsetTime
• java.time.Year
• java.time.YearMonth
• java.time.ZonedDateTime
• java.time.chrono.HijrahDate
• java.time.chrono.JapaneseDate
• java.time.chrono.MinguoDate
• java.time.chrono.ThaiBuddhistDate

at least, we should support

• [x] java.time.Instant (#197)
• [x] java.time.LocalDate
• [x] java.time.LocalDateTime
• [x] java.time.LocalTime (#197)
• [x] java.time.OffsetDateTime (#197)
• [x] java.time.ZonedDateTime

addition after 0.10.0

• [x] java.time.Year (#220)
• [x] java.time.YearMonth (#220)

Other than that?

I think in later stages java.sql.Timestamp could be useful. Although I think we should first focus on the ones that are listed under "at least, we should support", and later if it gets more traction slowly expand. Personally I think it is way more important to provide out of the box validation methods than 10+ different classes but only with rudimentary validation methods.
