Google-sheets – Google Sheet filling with minutes

google sheets

I've been struggling with this problems for ages and I can't find any solution.
Working on a Google Sheet I'm filling it with time in xx:yy format.

Google Sheet takes it as hours:minutes and I need to make it minutes:seconds.
So far I've been just writing 00:xx:yy, but with dozens of those times it would be way more simple to just edit/format it somehow.

So again: I need to edit/format the cells or even make a formula in another cell that converts 12:11 to 12 minutes and 11 seconds instead of 12 hours and 11 minutes.

Any help appreciated.

A formula to convert e.g. 12:11(:00) to 0:12:11 is quite easy:

=TIME(0,HOUR(A1),MINUTE(A1))
