How to display timestamps on activity feed

Question

I'm designing a mobile iOS app with a predominant focus on an activity feed of salespeople and customers. I'd like to place time stamps on each activity feed item, but am stuck deciding which format of timestamp is most easily read and understood.

My current implementation:

Twitter for iOS - very simple:

Facebook for iOS - wordy, literal

Answer 1

The standard abbreviation for minutes is min, it's familiar and not wordy. 3 min looks nice ). For easily read you should make it more noticable. Your tools are placement (+ alignment), font and color.

Bottom right placement is not so good, the number looks rather weird and floating.
