Dear David,

 

When I input the comman 'date "+%Y%m%d" -d "1986-05-04 1 day"' to get the
next day of '1986-05-04', I get the result as below.

Maybe it is a bug of Date command , Please help to find it, Thanks.

Thanks for the report.  However, it is most likely the only bug here is
your understanding of how date operates around daylight savings events:

It is considered poor netiquette to include employer disclaimers on mail
sent to publicly archived mailing lists, where the disclaimer is
rendered ineffective.  Consider using a personal account instead.

By coincidence I am not David either.  But will respond too anyway. :-)

I am confident that this is related to daylight savings time and that
it is answered in the FAQ.  Not having seen any activity on this issue
for a while I am going to close it in the bug tracking system.  Please
feel free to follow up if it has not answered your questions and the
group will see and read your message and the bug tracker will keep
track of it for us.

Bob
