But, get this:

$ PS1='$(date)\n\$ '
Tue Aug 30 09:30:37 EDT 2016
$ set -o igncr
-bash: command substitution: line 1: syntax error near unexpected token `)'
-bash: command substitution: line 1: `date)'

$ PS1='`date`\n\$ '
Tue Aug 30 09:31:01 EDT 2016
$

So, the $() syntax is part of the mix. Use back-ticks as a workaround.
