One thing I wish I could figure out is instead of showing UTC time, I wish I could display it in local time.
There's a setting for "offset from UTC time" (e.g., -7 hours for Pacific Daylight Time). That's what I was referring to above when I wondered why it doesn't already know your time zone.
You can access the Settings page for Tripmaster by tapping the lower-right box, and there are several Settings tabs stretching over two screens (be sure to click the >> tab to see all the settings available). I also changed the default time color (same as Units color) from red to yellow for better visibility.
