The MTA completed its goal of installing countdown clocks at all 471 of New York City's subway stations by the end of 2017, but how well they work is up for debate by straphangers.

According to a study released by the New York Post about the clocks, many don't display accurate arrival times.

In some cases, the clocks are located in obscure areas on the station platforms.

At the 6 train station in Hunts Point, commuters had mixed feelings but say the technology is helping transport the transit system into the modern era.

"From the time I was growing up they didn't have these clocks at that time, but now they're very helpful. They're really accurate. When they say two minutes they actually mean two minutes, except when there is a delay. But it tells you when it's a delay so it's very helpful," says one resident.

In a statement to News 12, MTA Spokesman Jon Weinstein says the agency is constantly making upgrades to the software of its new MTA Subway Time app and will continue to make regular testing a central part of the program to ensure the highest possible degree of accuracy.
