It has to do with how date(1) reads the command line. Basically, the '+ format' and '-f format date' options are not compatible. This appears to be a bug, but it would be really tricky to fix. (Hmm... maybe not...) Send in a PR if you would like so it gets into the system. Have a look at date.c. It is pretty clear what is happening. Feel free to submit a fix with a PR. -- Crist J.
