modify default call duration to 5 minutes (from 15)

Hello,

I know this subject is old but I already did all the changes in Datetimecombo.js & Time.js

 //A safety scan to make sure hrs and minutes are formatted correctly
	if (this.mins > 0 && this.mins < 5) {
		this.mins = 5;
	} else if (this.mins > 5 && this.mins < 10) {
		this.mins = 10;
	} else if (this.mins > 10 && this.mins < 15) {
		this.mins = 15;
	} else if (this.mins > 15 && this.mins < 20) {
		this.mins = 20;
	} else if (this.mins > 20 && this.mins < 25) {
		this.mins = 25;
	} else if (this.mins > 25 && this.mins < 30) {
		this.mins = 30;
	} else if (this.mins > 30 && this.mins < 35) {
		this.mins = 35;
	} else if (this.mins > 35 && this.mins < 40) {
		this.mins = 40;
	} else if (this.mins > 40 && this.mins < 45) {
		this.mins = 45;
	} else if (this.mins > 45 && this.mins < 50) {
		this.mins = 50;
	} else if (this.mins > 50 && this.mins < 55) {
		this.mins = 55;
	} else if (this.mins > 55) {
		this.hrs += 1;
		this.mins = 0;
and

if(this.allowEmptyHM){
		text += '\n<option></option>';
	}
	text += '\n<option value="00" ' + (this.mins == 00 ? "SELECTED" : "") + '>00</option>';
    text += '\n<option value="05" ' + (this.mins == 05 ? "SELECTED" : "") + '>05</option>';
    text += '\n<option value="10" ' + (this.mins == 10 ? "SELECTED" : "") + '>10</option>';
    text += '\n<option value="15" ' + (this.mins == 15 ? "SELECTED" : "") + '>15</option>';
    text += '\n<option value="20" ' + (this.mins == 20 ? "SELECTED" : "") + '>20</option>';
    text += '\n<option value="25" ' + (this.mins == 25 ? "SELECTED" : "") + '>25</option>';
    text += '\n<option value="30" ' + (this.mins == 30 ? "SELECTED" : "") + '>30</option>';
    text += '\n<option value="35" ' + (this.mins == 35 ? "SELECTED" : "") + '>35</option>';
    text += '\n<option value="40" ' + (this.mins == 40 ? "SELECTED" : "") + '>40</option>';
    text += '\n<option value="45" ' + (this.mins == 45 ? "SELECTED" : "") + '>45</option>';
    text += '\n<option value="50" ' + (this.mins == 50 ? "SELECTED" : "") + '>50</option>';
    text += '\n<option value="55" ' + (this.mins == 55 ? "SELECTED" : "") + '>55</option>';
    text += '\n</select>';
