Frequently asked questions
What about overnight shifts?
When the end time is earlier than the start time, the duration wraps to the next day. The result shows an "overnight" tag.
Why decimal hours?
Timesheets and billing tools usually accept decimal hours (8.5) rather than 8h 30m. Saves a conversion step.
