ALV Summarize TIMS field

Hi all

I have an ALV grid that shows time field from the data element TIMS(Char6 datatype).

Now it is not possible to summarize time in ALV with.

My question is, is there a way to summarize data element TIMS, like for example in this scenario, it should show in the first yellow row the time about 00:06:34 and etc.

Thanks for helping
