Date/time conversion specification compatibility
------------------------------------------------

OVERVIEW

This case extends the support for conversion specifications available at
libc date/time format conversion functions so that they will be more compatible
with other platforms such as glibc based Linux distros, MacOS X, and FreeBSD.
(Related compatibility CRs are shown at [1].)

In more detail, ascftime(3C), cftime(3C), strftime(3C), and wcsftime(3C) will
recognize and support 5 new conversion specifications (%+, %P, %s, %OB, %OV),
5 optional flag characters (#, -, 0, ^, _) governing padding and case
conversion behaviors, and optional field width as described in [2]. Also,
getdate(3C) and strptime(3C) will recognize and support 9 new conversion
specifications (%F, %g, %G, %k, %l, %P, %u, %V, %z) as described at [2].

This project imports no notable interfaces. This project exports:

    Interface             Stability     Note
    ---------             ---------     ----
    ascftime(3C),         Committed     See strftime.3c at [2] for first 3 API.
      cftime(3C),                       There is no update on the wcsftime(3C)
      strftime(3C), and                 man page; refer to strftime(3C) as
      wcsftime(3C)                      usual.

    getdate(3C)           Committed     [2]

    strptime(3C)          Committed     [2]

This project asks for Micro/Patch release binding.
