Back before the 2014 update. Halo Waypoint had a system where you could see the time and date a post was posted on.
Now you can only see the date the post was posted on(or just hours, minutes if it was posted under 24 hours ago)
I would like to suggest bringing back the time the post was posted on next to the date. This feature would be good for those who record posts. Plus seeing how long ago you last posted.
