Find the following code location, my js is around 1073
case 'span':
if (!target.is('.disabled')) {
var year = this.viewDate.getUTCFullYear(),
month = this.viewDate.getUTCMonth(),
day = this.viewDate.getUTCDate(),
hours = this.viewDate.getUTCHours(),
minutes = this.viewDate.getUTCMinutes(),
seconds = this.viewDate.getUTCSeconds();
Change the last line to data 0~59 to be written to death
case 'span':
if (!target.is('.disabled')) {
var year = this.viewDate.getUTCFullYear(),
month = this.viewDate.getUTCMonth(),
day = this.viewDate.getUTCDate(),
hours = this.viewDate.getUTCHours(),
minutes = this.viewDate.getUTCMinutes(),
seconds = 0;
// seconds = this.viewDate.getUTCSeconds();
Finish! Every time you select time seconds, it becomes a dead time
