Re: [icu-design] Proposal to support 64 bit time transitions in ICU

[Markus S. <mar...@gm...>]

Similarly compact, with greater range:

   - Store 2 or 3 UChars (16-bit units) per transition, big-endian style, in
   a resource bundle *string*.
   - Read 2 UChars into an int64 t.
   - If the last bit (bit 0) is 1, then t=(t>>1)*60 (31 signed bits for
   minutes granularity).
   - Otherwise, read another UChar c, then t=(t<<15)|c (*47 signed bits for
   seconds granularity*)

Smaller string padding in the .res file (compared with a binary) probably
outweighs larger storage in the longer form, and the 47-bit range is large
(+/- 2 million years).
