Orange and green icons on contact list

[Navalint]

Hi all,
I opened my contacts up and saw an orange clock icon on one of my contacts. Later the orange icon is gone but replaced with a green dot icon on the same contact. Both of these icons also showed up on the same contact in the stock messaging app as well. Can anyone tell me what these icons mean? I've had my phone since June and have never seen this before. I have an original Moto Droid through verizon if that helps.

they're Google Talk status icons. green dot means they're online, orange clock means they're unavailable.
