I have rest service which returns a collection of objects and one of the field of the item is a date string (ISO-8601 format ) and the date value as follows
You can pass another param to date pipe as follows:
{{resultItem.createdDate | date : 'short' : 'UTC'}}
This param can be a timezone like '-0430' or just 'GMT'
'-0430'
'GMT'
See documentation: https://docs.angularjs.org/api/ng/filter/date
