Description Florian Weimer 2018-03-14 08:09:02 UTC
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.
