amTimeAgo pipe returns "a few seconds ago" if the date property is missing

[iainbryden]

If the date property is missing amTimeAgo pipe returns "a few seconds ago"

The default date pipe just returns an empty string.

{{myItem.missingDate | date:'short' }}

Did you search for duplicate issue? Yes

Please describe the issue and steps to reproduce, preferably with a code sample / plunker:

export class MyClass {
    myItem = {name:'item'};
}

{{myItem.missingDate | amTimeAgo}}

output: 'a few seconds ago'

My work around is this:

<span  *ngIf="myItem?.missingDate">
    {{myItem.missingDate | amTimeAgo}}
</span>
