How do you remove the time stamp from facebook?

[Snowy]

I have someone on my friends list who has the mobile icon and when she logs in I see the green dot. When the green dot is gone the time is indicated like 1 min or 5 min and then it disappears and only the mobile icon is visible with no time stamp. I would like to remove the time stamp from mine but this person has not answered as to how they remove it. Could someone tell me?

that's just the last time her app was active, it doesnt mean she read anything

there is no way to just remove it
