When was my text message delivered? In the text messaging application that came with my Android phone, a checkmark seems to appear next to text messages that have been successfully delivered. How can I find out when a text message was delivered?

Update: The text messaging app might be a custom one. It's the default for Sony Ericsson Xperia X10 mini. A couple of screen caps I've found:
As soon as the check mark is appeared on the message text body, it means it delivered the message.

If you want a confirmation then you can use mysms SMS app. This could deliver the status message.

If you want to track the time when the SMS delivered then try SMS Scheduler. It keeps track of all your previous messages also.
