How to get time difference in ('h:m:s') between two times which are already in this format

I want to get difference between two times in hour:min:sec format. For Example starting time 02:00:00 and ending time 02:30:00 Difference should be 00:30:00

I tried to use Carbon but i think it support different format

<td> </td>

I want to get difference in hour:min:sec input would also be in same format
