TZ has for Colombia a single period with time zone 4h west.

# Rule  NAME    FROM    TO      - IN      ON      AT      SAVE    LETTER/S
Rule    CO      1992    only    -       May      3      0:00 1:00    -
Rule    CO      1993    only    -       Apr      4      0:00 0       -

I think the end date 4 April is wrong, it should be 6 February 24h or 7 
February 0h

The time shift was called Hora Gaviria, and caused by  shortage of 
electricity in connection with El Niño .

There is also a newspaper article

of 4 feb 1993, but the text is less clear to my limited understanding of 
Spanish.
