Data.Micro: microTruncate should probably stick to Int64
Data.Thyme.Calendar: yearMonthDay ∷ Simple Iso OrdinalDate YearMonthDay
Data.Thyme.Calendar.Internal: rename Week to WeekOfYear
Data.Thyme.Format: reimplemented class FormatTime; more instances
Data.Thyme.Clock.UTC: Day time part of UTCTime packing must be positive

∙ Worked fine for normalised UTCView, where dt >= 0.
∙ We abuse this when converting back from POSIXTime:
  ∘ Negative POSIXTime → negative dt → oops.
Data.Thyme.Calendar: instance Show Day where show = showGregorian
Data.Thyme.LocalTime: spawn Internal and TimeZone submodules
Data.Thyme.Clock: instance Show UTCTime
thyme.cabal: move library sources to src/
thyme.cabal: add flag(bug-for-bug)
Data.Thyme.Format: ISO 8601 specifies 4-digit years in the first millennium

∙ /bin/date behaves correctly in this regard.
Data.Thyme.Format: "%s" should probably round to 0, not down
tests/sanity.hs: correctness and speed
thyme.cabal: bump version to 0.1.2.0
