Function trial 

pub(crate) fn trial(now: &Zoned, tr: &Translator) -> Value

What a try hands Java (WakeAlarms.tryNow): {at, words}, the time it rings (Unix milliseconds, ten seconds on) and the words it says. Nothing of the night, its list or its next ring: a try is handed apart from them (sioul_android_wake_try, not sioul_android_set_wake) and rung by its own action and code, so the next waking stays as it is.
