Let us be more careful there. Although CSV has no formal specification 
(according to the IETF), *those spaces are not good*.

It is **very unlikely** that they will cause issues, but 1,10:24,20.4 is 
*safer* and - to my eyes - better CSV.

I wouldn't be surprised if a parser treated a value as text only because 
it has spaces on it.

For OP, if you are going for this, I - personally - suggest sticking to 
"%d,%2d:%2d,%.1f".
