This is quick and dirty:

# 1/72 is 20 minutes as a fraction of a day
if (-M '/tmp/file' > (1/72)) {
  # do stuff
}

-M returns the age in days of the file, but relative to the time that your program started. Therefore this works if your program is pretty fast and you're not too fussed about the accuracy of the 20 minutes. If that's not true then you'll also need to throw the value of $^T into the equation.
