The Cuban government’s decision to extend summer time to alleviate the electricity crisis clashes with device programming and further complicates daily life.

14ymedio, Havana, November 1, 2026 /Even knowing what time it is has become a problem in Cuba. This Sunday, numerous smartphones and computers woke up an hour behind the official time, after the automatic switch to winter time. The government had decided, however, to keep the clocks ahead in an attempt to alleviate the electricity crisis. The result has been a tremendous technological mess, with users searching for instructions, modifying settings, and asking for help to get their devices to obey the authorities.
In Luyanó, a Havana neighborhood, a resident insists that the elderly are among the most affected. “The old folks in the neighborhood who don’t know how to manipulate a phone are going crazy with the time change,” she tells 14ymedio. She herself has had to become an impromptu technician: “I already fixed mine and my mother’s.”
Faced with a avalanche of complaints, Etecsa issued an explanation this Sunday. In a statement published on Facebook, the company asserted that its technicians had worked for recent days to adapt the telecommunications systems and that the process was completed “satisfactorily.” However, it recognized that many phones did automatically change their time because their operating systems retained the previous settings. Its recommendation is to disable automatic time adjustment and manually advance the clock by sixty minutes.
“Out of the eight devices I have at home, I had to manually change the time on all eight!”
But the difficulties don’t end with finding the right settings. “Houston, we have a problem!” another user quips. “That claim that the time change was ‘successful’ needs an urgent review, because out of the eight devices I have at home, I had to manually change the time on all eight!” continue reading
From Sancti Spíritus, a resident explains that she set up her Xiaomi phone the night before, following the instructions, but the device still displayed the wrong time. “I had to put my foot down,” she summarizes.
The explanations have failed to appease the protests. Below Etecsa’s own statement, numerous complaints have accumulated from users who claim to have lost their mobile data connection, especially via the 4G network. “I called Customer Service and they told me I had to reconfigure the Nauta APN and restart my phone. I did that, and I’m still having problems,” says Sergio David Roche Díaz.
Another internet user adds a striking detail: “I have two lines on the same phone, and one works fine, but the other doesn’t.” There are also complaints about certain Cubacel numbers and Samsung models, which are unable to access the web browsing service this Sunday. Some recommend temporarily switching to the 3G network, while others claim they can’t connect using that technology either.
In a notice specifically for Cuba, Google acknowledges that the decision was announced too late to update Android before November 1st.
“I’ve tried thousands of times and my phone just won’t connect. It only works through tethering,” writes Yulieta Hernández Díaz. Elaine de Cárdenas Riol also says she can’t use Transfermóvil.
This newspaper had reported on the situation on Friday. Even Google had alerted users to the problem. In a specific notice for Cuba, the company acknowledges that the decision was announced too late to update Android before November 1st. As a temporary solution, it recommends selecting a time zone that remains in UTC-4, such as the Dominican Republic or Puerto Rico.
The problem reached international time zone authorities. On October 24, a user identified as Tuenvio sent an urgent request to the IANA public mailing list to warn of the Cuban decision. Two days later, specialist Tim Parenti confirmed that he had located the official announcement but warned of difficulties in distributing the update in time. The new version of the database was released on October 27. Microsoft also announced a fix for Windows during November.
The government estimates that maintaining daylight saving time will prevent a 126-megawatt increase in electricity demand during the evening peak. The measure will remain in effect until November 2027 and requires schools and workplaces to start half an hour later during the winter. For several weeks, the sun will not rise in Havana until after 8:00 a.m.
Morocco’s experience offers a warning.
The decision has precedent. In 2004, during another serious energy crisis, Fidel Castro’s government extended daylight saving time and modified school and work schedules.
Morocco’s experience offers a warning. In 2018, the North African country decided to permanently adopt summer time, also arguing that it would save electricity. However, after nearly eight years of controversy surrounding dark mornings and sleep disruptions, the government reversed course on September 20th. An analysis published in April 2016 estimated that the electricity savings represented only between 0.3% and 0.5% of national consumption. The Minister for Ecological Transition herself had acknowledged that no significant reduction in demand attributable to the measure was observed during the winter.
In Holguín, one resident interprets what happened as yet another example of official decisions that end up complicating daily life. “All they do is pretend to work. They spend the whole year inventing measures so that people think they’re doing something, but the measures end up creating more problems, like that infamous ‘Tarea Ordenamiento’ (Ordering Task),” he tells this newspaper. “Then come the corrections, and more measures. This is never-ending.”
Yanet Durán García, for her part, criticizes the institutions for not informing the public, especially the elderly, with sufficient advance notice. “Stop leaving the people to fend for themselves when it’s your responsibility,” she protests after spending the morning helping several neighbors.
But perhaps Mercedes Fundora Carrasco best sums up the mood of many Cubans. “For my part, I don’t care about any schedule if we don’t even have one anymore, and if we do, it’s only half the time,” she writes on Facebook. “My phone can change whenever it wants,” she adds, before mentioning that many workdays don’t even reach eight hours anymore. For many, the real problem isn’t that the phone is an hour behind, but that daily life stopped functioning normally a long time ago.
