Mr. maintainers:
        Hello! I am very glad to write this email to report my problem.
        When I am running commond on my server： 

~>date  -d "1940-06-01" +"%Y-%m-%d"
date: invalid date ‘1940-06-01’

but the other commond works right：
sense3:~>date  -d '1939-06-01' +"%Y-%m-%d"
1939-06-01
sense3:~>date  -d '1940-06-02' +"%Y-%m-%d"
1940-06-02
sense3:~>date  -d '1940-05-31' +"%Y-%m-%d"
1940-05-31
sense3:~>date  -d '1940-07-02' +"%Y-%m-%d"
1940-07-02
sense3:~>date  -d '1940-07-01' +"%Y-%m-%d"
1940-07-01
sense3:~>date  -d '1940-05-01' +"%Y-%m-%d"
1940-05-01

    my server's version and date version is：
~>uname -a
Linux zenglab 3.10.0-957.12.1.el7.x86_64 #1 SMP Mon Apr 29 14:59:59 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
