I do what OP does down to 30 min increments but I also bill a bit in how much cognitive power it required to do it. If I hopped on for 10 minutes to restart a server or something, I might bill 0 minutes or I might bill 30. If I had to drive out somewhere, live debug a device for 30 minutes, and drive back. I'm going to get an hour or two into my invoice somehow.
