Javascript for current Military Time with Rich Text Control in Repeating Section

Got this working with this code below. I just had to set the single line of text control to TimeL in the Client Id Javascript Variable Name field on the Advanced Tab.

Working code:

function myFunction() { var currentTime = new Date(),
hours = currentTime.getHours(),
minutes = currentTime.getMinutes();
 
 if (minutes < 10) {
 minutes = "0" + minutes;
}
 if (hours < 10) {
hours = "0" + hours;  

Revised the code and now it is working exactly like I wanted. When I click the Rich Text Button I added in the repeating section, I wanted the javascript to only update the specific Single line of text field within the current section the Rich Text button was clicked. The previous code would sometimes update the row before it, and also take 2 clicks to update the current row if the button was clicked on the 2nd and beyond repeating section row. The following code works on the last row. This assumes you follow the process of adding a repeating row and click the button on the empty section. Note: if you click add repeating row 2 times and then click the button in the second, row it will update the third row, but for the purpose my users will use the form, this will work just fine, becuase they will only add one row at a time and thus the button will update the last/current row:
