Understand the record
Starting now and backdating a start solve different problems. One begins a new record at the current clock time; the other makes the timer match a session you already began.
Use the controls deliberately
If the session genuinely began earlier, use the start adjustment controls and choose the correct date as well as the time. Future start times are rejected by the active controller.
For an active record, changing the goal preserves the start, note, mood, and optional weight. The controller also recalculates any enabled goal reminder, subject to permission and quiet-hour settings.
Check a practical example
For example, correcting 9:00 to 8:30 changes elapsed time by thirty minutes. It also moves the goal instant because the goal is measured from the stored start.

|---|---|
| Start now | Use current timestamp |
| Adjust start | Correct an existing fact |
Keep the meaning clear
Backdating is a correction tool, not a way to improve a displayed result. If you cannot remember the exact minute, record the uncertainty in a note instead of inventing precision.
