I'm not an expert on these things, but I don't believe so. acf/pacf doesn't require a ts object so it doesn't really need things to fit the exact nuances of the ts class. You may have to be a little careful in interpretation however depending on the nature of the irregular spacing, but that's going to be problem dependent.
Eitherway, take a look at the packages I endorsed in your other thread so you don't have deal with issues like "lying" to ts about your data.
