Linked pages available on Internet Archive: 
but Google Translate confirms they only reference Sixto hour in 1992.

Vaguely noted in Wikipedia Time in Ecuador article.
Ecuador Decreto Presidencial Nº. 285 de 1992 hora de Sixto
produces some useful links noting the dates above, and including Jaime 
Guevara song "Que hora es?" https://www.youtube.com/watch?v=ZfN4Fe_A50U
with written notes containing the above dates as well as the lyrics 
- should be added to tz-art; and one archived contemporary reference: 
http://www.eltiempo.com/archivo/documento/MAM-246470 via GT:
November 24, 1992
The energy emergency that the country is experiencing due to the 
reduction of rainfall in the areas where its main hydroelectric dams 
are located, yesterday forced the government of the president, Sixto 
Durán Ballén, to decree the advance of the official time, starting next 
day 28. The advance, in sixty minutes of official time to reduce energy 
consumption and take advantage of sunlight, is presented for the first 
time in Ecuador's history.

Take care. Thanks, Brian Inglis, Calgary, Alberta, Canada
