Localization

Day names, month names and the AM/PM indicators can be localized by passing an object with the necessary strings. For example:

var strftime = require('strftime');
strftime.i18n = {
    dayNames: [
        'Sun', 'Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat',
        'Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday'
    ],
    monthNames: [
        'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec',
        'January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December'
    ],
    timeNames: [
        'a', 'p', 'am', 'pm', 'A', 'P', 'AM', 'PM'
    ]
};

Notice that only one language is supported at a time and all strings must be present in the new value.
