title: Pygame time.get_ticks()
body: <p>I have difficulty understanding what the description of the function exactly means:</p>
  
  <p><strong>Return the number of millisconds since pygame.init() was called. Before pygame is initialized this will always be 0.</strong></p>
  
  <p>Can any one explain this with maybe an example? I tested the following one time with screen and once without it. When the screen line comes before <code>get_ticks</code> i will have some ms-values around 130-150 and when the screen line comes after the ms-value is about 19-20 ms. Why?</p>
  
  <pre><code>import pygame
  
  pygame.init()
  
  screen=pygame.display.set_mode((500,500))
  
  last=pygame.time.get_ticks()
  
  while 1:
      for e in pygame.event.get():
          if e.type==pygame.QUIT:
              pygame.quit()
  
      print last
  </code></pre>
