Convert to decimal hours - very simple, and in the long run you don't gain or lose any time.
I didn't think anybody worked in minutes any more? Hobbs meters are decimal.
To catch up on your past logged hours, you can use your pocket calculator. When entering 1 hr 13 mins, put in 10013, 1 hr 52 is 10052, and so on: then when you finish the page you have something like 240785, which would be 24 hours and 785 minutes. Take out 600 mins=10 hrs, leaves 185 mins. Take another 180 mins = 3 hrs, and your total is 37 hrs 5 mins.
