            Bug ID: 22964
           Summary: The Japanese Era name will be changed on May 1, 2019
           Product: glibc
           Version: 2.26
            Status: NEW
          Severity: normal
          Priority: P2
         Component: localedata
          Assignee: unassigned at sourceware dot org
          Reporter: fweimer at redhat dot com
                CC: libc-locales at sourceware dot org
  Target Milestone: ---

Yoko Oguma pointed out that glibc hard-codes information about the Japanese Era
name:

    era     "+:2:1990/01/01:+*:平成:%EC%Ey年";/
            "+:1:1989/01/08:1989/12/31:平成:%EC元年";/
            "+:2:1927/01/01:1989/01/07:昭和:%EC%Ey年";/
            "+:1:1926/12/25:1926/12/31:昭和:%EC元年";/
            "+:2:1913/01/01:1926/12/24:大正:%EC%Ey年";/
            "+:2:1912/07/30:1912/12/31:大正:%EC元年";/
            "+:6:1873/01/01:1912/07/29:明治:%EC%Ey年";/
            "+:1:0001/01/01:1872/12/31:西暦:%EC%Ey年";/
            "+:1:-0001/12/31:-*:紀元前:%EC%Ey年"

This will change due to the abdication.

commit 2f1d61552d429c4e1cbcec115f3cc3dcaf91400d
Author: TAMUKI Shoichi <tamuki@linet.gr.jp>
Date:   Tue Apr 2 16:37:03 2019 +0900

    time/tst-strftime2.c: Make the file easier to maintain

    Express the years as full Gregorian years (e.g., 1988 instead of 88)
    and months with natural numbers (1-12 rather than 0-11).

    Compare actual dates rather than indexes when selecting the era name.

    Declare the local variable era as a string character pointer rather
    than an array of chars where the actual string is copied which might
    lead to potential buffer overflows in future.

    ChangeLog:

        (dates): Use natural month and year numbers to express a date.

        (do_test): Reflect the changes in dates array.
