Time to WIN calculates the total time from a given list of time ranges, automatically subtracting breaks:
- 15 min between 9:15 and 9:30
- 30 min between 12:00 and 13:00.
Timestamps are expected in the format hh:mm, or now for the current time. Timestamps and ranges have to be ordered in time.
All calculations are done in the browser, no input data is sent to remote servers.
