In December 2006 I described a "proleptic UTC" which quantized UTC's
rubber seconds era of the 196s0 in the style of post-1972 UTC.

The idea was to allow a software system that knows about TAI and modern
UTC to be able to describe times in the 1960s accurate to about 1s, and
smoothly blend back to the pre-atomic era in which it ignores the
differences between UTC and TAI.
