--- Comment #4 from Ondřej Kuzník ondra@mistotebe.net --- As seen in another MR I had experimented with this, and should be easy enough, apart from the fact that historically a value of != 0 means allow that amount of seconds as a difference. So a 0 is both a default and meaningful config we'd be making fall back to frontend's precision.
Not sure that's a reason against since ways to achieve that configuration still exist.
