PS: there is also an English version of the respective WP page


It has an interesting statement:

> Of Colombia's 1,024 municipalities, 1,000 declined to change time 
> zones and took months to come into effect.
the Spanish version in WP makes no sense when it says:

> La medida conocida como "Hora Gaviria 
> <https://es.wikipedia.org/wiki/C%C3%A9sar_Gaviria>" comenzó a las 
> 12:00 AM del 2 de mayo <https://es.wikipedia.org/wiki/2_de_mayo> de

> los 1.024 que tenía el país en ese momento se negaron a cambiar a la 
> zona horaria y solo se ajustaron a la medida diez meses después
y solo se ajustaron a la medida diez meses después = and they were only 
fitted to the measure ten months later. because 10 months after may 1992 
we are in March 1993, and by that time the measure had already ended.

But that is of little concern for TZ, as it only wants to know about 
Bogota. The capital was certainly among the few communes who followed 
the law.

It will be hard to research which parts of the country adopted the 1992 
time shift at which point. This being after 1970, TZ should in principle 
represent the division of the country into areas with different time
