Timeless Time & Expense will assist you in correcting overlapping entries. If you create a new time entry that overlaps another, you will be given the option of how to correct the overlap.
To demonstrate, create a new time entry that goes from 9:00 - 11:00. This will overlap with our existing entry from 8:00 - 10:00. Press OK. When prompted, choose to adjust other time entries. Look at the time entries. You notice that the first entry was automatically adjusted to end at 9:00.
This is especially useful when you forget to start a timer. By adjusting the start time of the running entry, you can correct both entries at once.
