ruby - Rails: Get the DateTime format returned using Jbuilder -


i noticed when returning field type datetime in jbuilder : "2016-11-25t13:25:06.024z"

but when in .html.erb page display field "2016-12-21 09:35:05 utc"

my question how format of jbuilder in html.erb.

what you're seeing in json standard iso-8601 formatted timestamp time in utc (hence z). can format in rails conveniently named iso8601 method:

> time.now.utc.iso8601  => "2016-12-22t04:59:25z"

the utc call there ensure time in utc, don't need doesn't hurt , can prevent problems.

if want match precision you're getting jbuilder, include precision in iso8601 call:

> time.now.utc.iso8601(3)  => "2016-12-22t05:01:21.512z"
