Question: At what local time does the country where Fuser and Alberto meet the indigenous couple traveling to look for work change their clocks for DST?

During their expedition, Guevara and Granado encounter the poverty of the indigenous peasants, and the movie assumes a greater seriousness once the men gain a better sense of the disparity between the ``haves ''(to which they belong) and the obviously exploited`` have - nots'' (who make up the majority of those they encounter) by traveling on foot. In Chile, for instance, they encounter a penniless and persecuted couple forced onto the road because of their communist beliefs. In a fire - lit scene, Guevara and Granado ashamedly admit to the couple that they are not out looking for work as well. The duo then accompanies the couple to the Chuquicamata copper mine, where Guevara becomes angry at the treatment of the workers. [SEP] Knowledge 2: Daylight saving time
Beginning and ending dates are roughly the reverse in the southern hemisphere. For example, mainland Chile observed DST from the second Saturday in October to the second Saturday in March, with transitions at 24:00 local time. The time difference between the United Kingdom and mainland Chile could therefore be five hours during the Northern summer, three hours during the Southern summer and four hours a few weeks per year because of mismatch of changing dates.

Xinjiang, China; Argentina; Chile; Iceland; Russia and other areas skew time zones westward, in effect observing DST year-round without complications from clock shifts. For example, Saskatoon, Saskatchewan, is at 106°39′ W longitude, slightly west of center of the idealized Mountain Time Zone (105° W), but the time in Saskatchewan is Central Standard Time (90° W) year-round, so Saskatoon is always about 67 minutes ahead of mean solar time, thus effectively observing daylight saving time year-round. Conversely, northeast India and a few other areas skew time zones eastward, in effect observing negative DST. The United Kingdom and Ireland experimented with year-round DST from 1968 to 1971 but abandoned it because of its unpopularity, particularly in northern regions.

DST's clock shifts have the obvious disadvantage of complexity. People must remember to change their clocks; this can be time-consuming, particularly for mechanical clocks that cannot be moved backward safely. People who work across time zone boundaries need to keep track of multiple DST rules, as not all locations observe DST or observe it the same way. The length of the calendar day becomes variable; it is no longer always 24 hours. Disruption to meetings, travel, broadcasts, billing systems, and records management is common, and can be expensive. During an autumn transition from 02:00 to 01:00, a clock reads times from 01:00:00 through 01:59:59 twice, possibly leading to confusion.

Answer: 24:00
