How can i add up times with format "mm:ss,000"?

Hi!

I want to be able to add up times with minutes, seconds and milliseconds.

That is easy to get in Excel by formatting cells as mm:ss,000, but Zoho Sheet doesn't recognize it where import the .xsl file. I was looking all different options but I did not find how to format cells like this way.

For example:

1:29,002
1:32,010
--------------
3:01,012

Any workaround?

Thank you very much.
