Ask HN: Time tracking software recommendations?

It's been a while since I've seen some time tracking recommendations here. I am having to track time across a few projects recently - was previously on a single project full time.

I'm familiar with some of the baked in solutions that come with Freshbooks/Basecamp and I've seen Freckle. Just wanted to see if anyone has come across any new players in the space. Looking for something simple - hours worked, project name, task name. CLI interface would be awesome, but not a requirement, especially if there's a decent app offering.

Any recommendations/success stories appreciated.
