(Eg: 242235.34234) The input and the model values do not match. HTML

问题 I'm trying to convert a timestamp to a date format using Angular pipes. I wrote this in the HTML template: {{myTimestamp | date}} Where myTimestamp is of type number. I get unexpected results, for example the timestamp 1468251287 (Which matches Nov 7, 2016) is displayed as Jan 18, 1970 .

问题 I need to determine whether two different approaches for handling Observables are equally valid, or if one will cause memory issues. In the following example, foo$ and bar are template variables that receive their values from a service. Each has its own Observable.
