You're 100% wrong. You argue as if there are options in how to represent 
UTC. There aren't. That's made clear by ITU-R TF.460-6, which defines 
UTC: "A positive leap-second begins at 23h 59m 60s and ends at 0h 0m 0s 
of the first day of the following month. In the case of a negative 
leap-second, 23h 59m 58s will be followed one second later by 0h 0m 0s 
of the first day of the following month."
