FAQs
Can the end be before the start?
No. The end must come after the start; if your dates are the wrong way round, simply swap them.
Which time zone is used?
Your device’s local time zone applies to both the start and the end, so the duration is the elapsed time where you are.
How are the totals formatted?
Total hours are shown to two decimal places and total minutes to one, making them easy to use in timesheets and billing.
