Moment.js amDateFormat always returning date from 1970

问题

http://plnkr.co/edit/5zxXEEz30t51yGhgYWVF?p=preview

I'm using Moment.js and Angular-moment in my app.

For some reason it's converting all my epoch timestamps to the same date from 1970.

<td class="timespan">{{tag.added_epoch | amDateFormat:'dddd, MMMM Do YYYY'}}</td>

This is what the tag.added_epoch value is added_epoch: 1432252800

However when I convert it online, I get the correct date:

Any idea why my filter is turning 1432252800 into Saturday, January 17th 1970?

回答1:

I'm just quickly summarizing the problem and solution.

Moment.js offers two different ways to create a date from a unix timestamp moment(1432252800) and moment.unix(1432252800).

Both start at the same time (Jan 1 1970 12AM UTC) but moment() uses the number as milliseconds, which are around 17 days and moment.unix() uses seconds.

angular-moment supports the amFromUnix filter, see source

You can use it the following way

<time am-time-ago="myDate|amFromUnix">
{{myDate|amFromUnix|amCalendar}}

回答2:

Try to write own filter, like this:

 newapp.filter("fromTimestamp", function(){
   return function(timestamp, format){
     return moment.unix(timestamp).format(format)
   }
 })

And use them

<p class="date">{{date | fromTimestamp:'dddd, MMMM Do YYYY'}}</p>
