The timepicker.timeRange is not work after i changed the endtime to 00:mm;

[HOLYYUN]

I use the timepicker to set starttime and end time in this core
$.timepicker.timeRange($('#FirstDateTimeBegin'),$('#FirstDateTimeEnd'), { minInterval: (1000 * 60 * 60), // 1h timeFormat: 'HH:mm', start: {}, // start picker options end: {} // end picker options } );
if i don't set endtime to 00:mm,it's worked; After i set the endtime to 00:mm,it's not worked again。
it's also happend at the examples http://trentrichardson.com/examples/timepicker/
