Someone brought this up to me in conversation and asked if there was a way to remove the time stamp.
Facebook will always show a time stamp for your status. There's no way to remove it. It's not a worry for me, but I can see how it might be for some people. It will also always show a time stamp when you post on someone's wall. However, you can take off the time stamp on your news feed and wall for all other Facebook actions.
- Click on Settings
- Click on "manage" next to Privacy
- Click on "News Feed and Wall"
- On the bottom of the left-hand column there is a check box you can un-check that says "Show times in my Wall"
