Please do not, unless you are actually implementing unit conversion logic. Pass around types encoding certain quantities. You do not want a Thread to "sleep for x units", but rather "sleep for this specific Duration", therefore pass around Durations and implement appropriate utilities `.toSeconds(Duration d)`, `.fromTime(Time t1, Time t2)`. The very moment your `.frobnicate(int time_in_seconds)` gets wrapped in `foobar(int duration)` all meaning is lost and you have no control over it. Type systems are there to encode meaning (sometimes including possible values) behind a value - use it. And if you use highly dynamic prototyping language in production... Well, inability to encode and enforce meaning behind a value is part of the compromise.
