Steps to reproduce the problem:
1. Call interface "chrome.devtools.network.getHAR" from devtools_page to dump the HAR log.
2. startedDateTime fields exposed as Object

What is the expected behavior?
- startedDateTime should be a String as exposed by the HAR 1.2 spec, e.g startedDateTime : "2018-02-27T10:47:25.488Z" 

What went wrong?
startedDateTime is an Object :: {}
Which results in a HAR bad format (attached file)

Did this work before? No
