Iron doors...Dragons eye level 3

[Charlotte]

Hi!

I cant find the lever to open the iron doors on this level. I then have to wait for a timer that opens the doord ever 24 hours...But which hour is it?? Is at 4 o clock, 6 oclock...? Have tried at 0 hours, but nothing happens! Which is it? Can anyone tell me or give me a trick to open these damn doors!!!! : / Are they important for the rest of the game??
