Overlap notifications and entries that spill into the next day
Sandtime.io warns about overlapping activities because they can distort reported time.
What counts as an overlap
Two of your entries overlap when one starts before the previous one has ended. Sandtime.io sorts your entries by start time and flags any adjacent pair where that happens, so an overlap always names two specific entries rather than marking the day as a whole.
It is worth clearing rather than tolerating: the overlapping stretch is ignored, so the reported time stops matching what the entries appear to add up to. A timesheet that looks complete can still be wrong.
Disable overlap notifications
Open Settings > Notifications and find the Overlap detected row. Email and dashboard alerts have their own checkboxes, so you can stop the emails and still see overlaps on your dashboard.
Keep in mind that silencing the warning does not remove the overlap itself. It only changes the notification behavior.
The overlap stays visible after the emails stop
Turning the notification off does not hide the overlap where the numbers are. The warning still shows on the timesheet, on the dashboard, and on the report column the overlapping entries fall into, so the record itself keeps saying that two entries disagree.
Clearing an overlap
Adjust one of the two entries so they no longer meet: move a start time later, pull an end time earlier, or shorten a duration. See Edit or delete a time entry for the steps. Deleting one of them works too when it turns out to be a duplicate.
Why an entry can extend into the next day
Entries follow their start and end times. If the selected duration or end time pushes work past midnight, the entry can naturally continue into the next day.
There is no separate "do not move to the next day" switch for that behavior. If you want to avoid the spillover, shorten the duration or adjust the time range manually.
