The unary plus operator –

<http://ecma-international.org/ecma-262/7.0/#sec-unary-plus-operator>

– is unnecessary as the “/” operator is a Multiplicative Operator (like “*” 
and “%”) that already converts its operands to Number:

<http://ecma-international.org/ecma-262/7.0/#sec-multiplicative-operators-runtime-semantics-evaluation>

And since a UNIX timestamp has only seconds, it is debatable whether it 
should not be Math.floor(…) instead of Math.round(…).
