CurrentNtp return time by taking two output parameters by reference (also breaks style guide) CurrentNtpTime treat ntp time as single entity and returns it using NtpTime structure. (making interface clearer) BUG=None Review-Url: https://codereview.webrtc.org/2733823002 Cr-Commit-Position: refs/heads/master@{#17088}
