observ-at

observ values that keep track of time.

Usage

var ObservableAt = require('observ-at');

// observ-at has the same interface as observ

var value = ObservableAt(0);

value(function (v) {
	console.log('value changed:', v);
});

value.set(1); // Prints "value changed: 1"

// But an optional parameter can be added to specify the time of the update

value.set(2, Date.now()); // Will update value
value.set(3, Date.now() - 3600); // Won't update value
