Class Method Details

.parse(hhmm) ⇒ Object

hhmm is a string containg an hour-and-minute value

#parse will remove all nondigit characters, pad the result to 4 digits, and interpret the first two as an hour value, the last two as a minute value

padding takes place as follows :

* one digit becomes 0d00 (assumes "7" means "0700")
* two digits become dd00 (assumes "11" means "1100")
* three digits become 0ddd (assumes "830" means "0830")
