Update date format in for logs

[Ed Benckert]

Reminder re: email I sent. Date format in logs is ugly, updating the default to [{0,2:00}:{1,2:00}:{2,2:00}] is a better format. Better yet, update to use hh:mm:ss as per email.

[{0:00}:{1:00}:{2:00}] seems to work well, not sure how to use hh:mm:ss in a way that doesn’t break backwards compat?
