bash - Strange behavior for the date() function linux -


this question has answer here:

i have found strange behaviour date() function when using bash. when use date -d "2008-10-12 +1 days", date function returned

date: invalid date ‘2008-10-12 +1days’

even returned error when trying:

date -d "2008-10-12" --> date: invalid date ‘2008-10-12’

however, works for:

date -d "2008-10-13 +1days" --> tue oct 14 00:00:00 clst 2008

date -d "2008-10-11 +1days" --> sun oct 12 01:00:00 clst 2008

date -d "2007-10-12 +1days" --> sat oct 13 00:00:00 clt 2007

... , on

it seems date() not recognize "just" 2008-10-12. bug? doing wrong?

i using centos 7

all best

in rhel 7 there many changes happened somany commands. change time , date earlier used use date command , need use timedatectl command (preferred) instead.

http://www.freedesktop.org/software/systemd/man/timedatectl.html

so there new latest command more features included might have limited (not sure on that). version have been using timedatectl command great one.
