I am getting errors on the date
command if I use the timezone designation stored in the system:
$ date -d "2019-12-10 23:26:30 EDT +4 hours"
date: invalid date ‘2019-12-10 23:26:30 EDT +4 hours’
$ date -d "2019-12-10 23:26:30 EST +4 hours"
Wed Dec 11 03:26:30 EST 2019
Here's what I get when I ask to display the time zone information:
$ date +"%Z %z"
EDT -0400
Is this an error on my part or has something changed in the system?
I am running Ubuntu 18.04.4 LTS x86_64 with kernel 5.7.1-050701-generic.
