Yes, but not the time so much. The dish itself is not a good conductor of heat, like cast iron or other metal for example. And it allows radiant heat directly on what is being cooked. One thing I do is that I have a pizza stone in my oven that helps keep the oven temperature stable.
Another thing that is very common is that oven temperatures are notoriously inaccurate. So, it pays to use an oven thermometer in order to get accurate oven temps (instead of going by the oven temperature dial).
Here's another tip. Place a cookie sheet on the rack below the glass/pyrex baking dish. This keeps the radiant heat from the lower element from directly heating the dish.
I must say though, that the #1 thing that has improved my baking is the oven thermometer. The oven dial in my kitchen is off from 15 to 25 degrees. This is a tip I got from "On Food and Cooking" by Harold McGee. The second thing is the pizza stone that helps regulate the temperature. A standard oven cycles on and off to maintain the temperature.
All that being said, I'd use metal cookware for cake. But I do get good results when I wind up using glassware by controlling the oven temps.
Update I made brownies last night and noticed in Marion Cunningham's (The Fannie Farmer Cookbook) recipe this advice, "If you're using a Pyrex dish, place it on a baking sheet during baking". What that does is to act as a buffer between the heating elements and the dish.
The very first thing to do is to put an oven thermometer in your oven and find out if your thermostat is accurate. It will take a little while to do this test, because the oven will first overheat then cool then overheat, etc. After 20-30 minutes, you should get a good reading as the interior heats up and the temperatures fluctuations subside. If your reading on the thermometer is different from the t-stat setting, then you will be able to compensate.If it won't hold a steady temp, you should replace the thermostat Sometimes you can recalibrate a home oven t-stat, but it might cost more than it's worth as long as you allow for the discrepancy.

I wouldn’t change much if anything.
The main factor for baking is volume and the area of the cross-section, or, in other words, how long does it take for the oven heat to reach the center parts of the batter and bake them. Under that premise, you could say a bundt pan is like a curved loaf pan, thanks to the chimney in the middle. But: The material of the pans will also be a factor in baking time, even if you are using the same shape, so a tiny bit of experimentation is called for here
So the recommendation is to treat your tried-and-tested recipe like a new one: Set your timer for about five to ten minutes less than you normally would, check the cake for doneness (thermometer or skewer that comes out clean) and if needed, continue baking until the cake is done. Tip: note the baking time for all pans that you used, this will be helpful next time.
Assuming that you are baking the pound cake at a relatively low temperature (160-175 C or 325-350 F), a few minutes deviation won’t cause it to burn.
