Lets see. There have been nine leap seconds in 20 years. So at the start of the next century the difference will probably be less than a minute There is no predicting how large the decadal variations in LOD will be, but the difference should be somewhere between 1 minute and 3 minutes. Please see these charts and tables for how unpredictable it is. http://www.ucolick.org/~sla/leapsecs/dutc.html
Remember OpenTime is only for people who want their system clocks to ignore leap seconds. I don't include myself among the possible users of OpenTime. Anyone who needs that can already do that using existing, deployed, and tested code and hardware and the GPS system time scale. Please see this worked example. Please do not invent yet another private time scale. http://www.ucolick.org/~sla/leapsecs/right+gps.html

So basically the concept of OpenTime is already implemented. All that's needed is a list of Stratum-1 servers that anyone can use.
