How it works
Weeks, days, hours, minutes, and seconds are exact. In the humanize direction, units above your "largest unit" are rolled into it (for example 90000 s as hours becomes 25h). In the parse direction, colon input is read as MM:SS, HH:MM:SS, or DD:HH:MM:SS, and token input accepts forms like "1.5h", "90 min", or "2 hours 30 minutes".
