Science and Technology Minister Hector Nacarro praised the measure.
"I see it as a very positive thing that while there is light we can be in it," he said.
And President Chavez said earlier this year that schoolchildren would arrive for lessons with more energy as a result of the change.
"These children have to get up at five in the morning... they arrive at school dead tired. And why? Because of our time."
Fiendish time! It's ruining everything!
Actually, this isn't the only half-hour-off time zone:
Canada's Newfoundland province is half-an-hour out of step with other Atlantic provinces.
Pakistan is only half-an-hour behind India, while Nepal is a mere 15 minutes ahead of its large southern neighbour.
Western Australia and South Australia observe a 90-minute time difference across the state boundary.
However, the remote border town of Eucla and the surrounding area, home to a few hundred people, operates on its own time zone, 45 minutes ahead of Western Australia and 45 minutes behind South Australia.
