I liked David Johnston's even stronger suggestion upthread: make it an
error to specify a value requires rounding of any kind. In other
words, if the minimum granularity is 1 minute, you can specify that as
60 seconds instead, but if you write 59 seconds, we error out. Maybe
that seems pedantic, but I don't think users will much appreciate the
discovery that 30 seconds means 60 seconds. They'll be happier to be
told that up front than having to work it out afterward.
