Approximately 10 months for the Russians - The Mars 96 Orbiter was a 3-axis sun/star stabilized craft based on the Phobos design with two platforms for pointing and stabilizing instruments. The propulsion units were mounted on the bottom and two large solar panels extended out from opposite sides of the craft. The two penetrators were mounted on the bottom by the propulsion system, the two small stations were connected on top of the spacecraft, and a dish antenna extended off one of the sides perpendicular to the solar panels. The Mars 96 spacecraft had a launch mass (including propellant) of 6180 kg. Mars 96 was scheduled to arrive at Mars on 12 September 1997, about 10 months after launch, on a direct trajectory. About 4 to 5 days before arrival the small surface stations would have been released. The orbiter was to go into an elliptical 3-day transfer orbit about Mars, and the two penetrators to descend to the surface during the first month of orbit. The final orbit would have been a 14.77 hour elliptical orbit with a periapsis of 300 km.
Approximately 305 days for the US of A -
From NASA Report, 1996 Mars Missions Trans-Mars cruise. The spacecraft will take between 301 and 309 days to reach the red planet on a flight path known as a Type 2 trajectory, depending on the Earth departure date within the 20-day launch period. A Type 2 trajectory takes a spacecraft more than 180 degrees around the Sun and, compared with other trajectories, is a slower way to reach Mars. However, because the spacecraft is traveling at a slower velocity, it will require less propellant to slow down once it is ready to be captured in orbit around the destination planet. A launch at the opening of the launch period on November 6, 1996, would result in a Mars arrival date of September 11, 1997, while a launch at the close of the period on November 25, 1996, would result in arrival on September 22, 1997.

6 Months each way at the present time. BUT you'd need to stay there for some 18 Months before it came again into a position where you could travel back.
Think of the quantity of Oxygen and food and water you'd need for that time
Think too of being in a tin can with a few other people for 2 1/2 years. You'd all go nuts if you didn't die of solar radiation first as Mars has no magnetic field to deflect it.
A lead lined spaceship would be awful heavy!

MANY years (if you include astronauts); not before 2050 i think. But it very well can take up to 2100.
Only if terrorists and wars do stop, we'll get the means to spend enough on big spaceships.

ABOUT 14 MINUTES, IF YOU TRAVEL AT THE SPEED OF LIGHT.

Just cross the road to your local shop, they stock plenty of bars of them.

I've heard that it's 6 months each way.
