ENH: TimeDeltaIndex and corresponding scalar (original) (raw)

Description

• disallow operations in series that are invalid that now create timedelta64
  (e.g. dt + dt, only dt - dt?) BUG/API: Fix operating with timedelta64/pd.offsets on rhs of a datelike series/index #4534
• create the TimeDeltaIndex object, inherit from Int64, ENH: create Timedelta scalar / TimedeltaIndex #8184
• create associated scalar (np.timedelta64 wrapper), like
  Timestamp (Timedelta?), direct wrapper might work, ENH: create Timedelta scalar / TimedeltaIndex #8184
  that forwards methods, internally repr as timedelta64 (or view?) as array
• move pretty printing to the new class (from function in lib), done???
  see Weird Datetime Behaviour #3002 and ENH: support min/max on timedelta64[ns] Series #2990, ENH: timedelta should write correctly to csv #4378
• need a Timedelta64 Block, with to_native_types (for printing), PR ENH: GH3371 support timedelta fillna #4684
• read_csv to have a parse_timedelta to automatically apply the dtype, see API: add parse_timedelta kw for read_csv #4650, ENH: GH3371 support timedelta fillna #4684, moved to ENH: read_csv to have a parse_timedelta kw to automatically parse into timedelta64 #8185
