How to bind the URL of a GridView HyperLinkField when the bound value contains a colon?

I’m trying to bind a GridView HyperLinkField such that the bound column is used as a parameter value in the URL. Pretty standard stuff – nothing fancy, but the binding fails when the bound column contains a colon, i.e. :. I’m my particular case, this value is a string representing a duration of time, e.g. “14:35”, or “1:07:19”.
