Time Log entries are not very intuitive to edit, as they display measured time in hours and minutes (correct), but if you do want to edit the time entry, it will display the value as a rational number.
Example: 1h 40minutes is displayed, but if you would like to edit that time entry by double-clicking on the value, the entry field will change and display "1.67" which is effectively 1h and 40minutes.
And now imagine you need to edit the original entry to 1h54minutes. Then it starts to be a little nightmare.
Can you please fix this?
