There's a movie I saw as a kid with a group of humans who are being chased through space by space pirates. At one point, they encounter an anomaly that speeds up time. One of the lady's gives birth and the kid grows up within a few minutes to save the ship.

Anyone know what this is?

Ice Pirates
The Ice Pirates (1984) (http://amazon.imdb.com/title/tt0087451/)

The Pirates are the good guys and are the ones being chased. :)
