time_format 2 tabulation is off

See example:

```
  ->  1h 43m 21s    B    Task1
           1h    B    Task2
          15m    B    Task2
          45m         Non-billable item
```

Ideally hours/minutes and seconds should be in the same columns

```
  ->  1h 43m 21s    B    Task1
      1h            B    Task2
         15m        B    Task2
         45m             Non-billable item
```
