Do we? I think what you really want is to equalize the amount of solar radiation hitting all sides. And if I can build a planet-sized solar shade, well, why not go one step further and instead make a swarm of mirrors in orbit?
When they orbit the sun-facing side, they reflect the light away from Venus. When they're opposite, they're in darkness anyway. But when they're in between, they reflect light towards the dark side of the planet!
I choose the angle of every mirror in this swarm, and thus I choose the amount of solar radiation hitting each point on the planet at all times. Thus, Venus shall have one timezone, Venus Standard Time, and I swear to you it shall not have anything like Daylight Savings Time.
Not necessary, but convenient. Venus has very little water, so maybe impacting comets at the equator in the right direction would be enough to solve both problems
